mole is short for molecular. they are basically one in the same. the molecular mass is in amus, the average mass unit, and the mole is a number that converts amus to grams. a mole is the amount of particle in 12 grams of carbon-12, best explained by avagadros number: 6.022*10^23. this is to say molecular mass is the mass of a molecule, and the molar mass is the amount of moles. so there would be 10 moles in 10 grams of Hydrogen. and a molecule of hydrogen, H2, would be 2.014 amu.
What else can I help you with?
Which mathematical relationship should you use to convert moles of a substance into grams?
You can use the molar mass of the substance to convert moles into grams. This involves multiplying the number of moles by the molar mass of the substance, where the molar mass is expressed in grams per mole. This relationship allows you to convert between the two units.
What is the average velocity of atoms in 2.00 mol of neon at 308 K?
The root mean square velocity of atoms in a gas can be calculated using the formula: vrms = sqrt((3kT)/m), where k is the Boltzmann constant, T is the temperature in Kelvin, and m is the molar mass of the gas. For neon with a molar mass of 20.18 g/mol, the vrms at 308 K would be approximately 516 m/s.
What is the relation between sound and the temperature of material?
The speed of sound in a material is influenced by its temperature. In general, sound travels faster in materials at higher temperatures due to increased molecular motion. This relationship is described by the formula v = √(γRT/M), where v is the speed of sound, γ is the heat capacity ratio, R is the gas constant, T is the temperature, and M is the molar mass of the gas.
What is the heat capacity of argon and how does it compare to other gases?
The heat capacity of argon is relatively low compared to other gases. It has a molar heat capacity of 20.85 J/molK at constant pressure and 12.48 J/molK at constant volume. This means that argon requires less energy to raise its temperature compared to other gases like nitrogen or oxygen.
A gas consists of a mixture of neon and argon The rms speed of the neon atoms is 350 What is the rms speed of the argon atoms?
The root-mean-square (rms) speed of a gas molecule is proportional to the square root of its temperature and inversely proportional to its molar mass. Since neon and argon gases are at the same temperature, the ratio of their rms speeds will be the square root of the ratio of their molar masses. Therefore, to find the rms speed of argon atoms, you need to calculate the square root of the ratio of the molar masses of argon to neon (molar mass of argon/molar mass of neon) and multiply it by the rms speed of neon.
What is the relationship between the molar mass of a gas and its density?
The relationship between the molar mass of a gas and its density is that as the molar mass of a gas increases, its density also increases. This means that gases with higher molar masses will be denser than gases with lower molar masses.
What is the relationship between the molar mass of a gas and its behavior according to the ideal gas law?
The relationship between the molar mass of a gas and its behavior according to the ideal gas law is that lighter gases with lower molar masses behave more ideally than heavier gases with higher molar masses. This means that lighter gases are more likely to follow the predictions of the ideal gas law, which describes the behavior of gases under certain conditions.
What is the relationship between molality and molar mass in a solution?
The relationship between molality and molar mass in a solution is that molality is directly proportional to molar mass. This means that as the molar mass of a solute increases, the molality of the solution also increases.
What is the relationship between freezing point depression and molar mass?
The relationship between freezing point depression and molar mass is that the freezing point depression is directly proportional to the molar mass of the solute. This means that as the molar mass of the solute increases, the freezing point depression also increases.
What is the relationship between the molar mass of a substance and its equivalent in daltons?
The molar mass of a substance is equal to its equivalent in daltons.
What is the relationship between molar mass and density in a substance?
The relationship between molar mass and density in a substance is that as the molar mass of a substance increases, its density also tends to increase. This is because a higher molar mass means there are more particles packed into a given volume, leading to a higher density.
What is the relationship between electrolyte concentration and molar conductivity?
The relationship between electrolyte concentration and molar conductivity is that as the concentration of electrolytes increases, the molar conductivity also increases. This is because more ions are available to carry electrical charge, leading to higher conductivity.
What is the relationship between the molar mass and freezing point depression of a substance?
The relationship between the molar mass and freezing point depression of a substance is that the freezing point depression is directly proportional to the molar mass of the solute. This means that as the molar mass of the solute increases, the freezing point depression also increases.
What is the relationship between the molar mass and molality of a solution?
The relationship between the molar mass and molality of a solution is that the molality of a solution is dependent on the molar mass of the solute. Molality is calculated by dividing the number of moles of solute by the mass of the solvent in kilograms. Therefore, the molar mass of the solute directly affects the molality of the solution.
What is the relationship between the molar mass and density of a substance?
The relationship between the molar mass and density of a substance is that the molar mass affects the density of a substance. Generally, substances with higher molar masses tend to have higher densities. This is because the molar mass represents the mass of one mole of a substance, and denser substances have more mass packed into a given volume.
What is the relationship between the molar mass and freezing point depression in lab answers?
The relationship between molar mass and freezing point depression in lab answers is that the freezing point depression is directly proportional to the molar mass of the solute. This means that as the molar mass of the solute increases, the freezing point depression also increases.
What is the relationship between temperature and molar entropy in a chemical system?
The relationship between temperature and molar entropy in a chemical system is that as temperature increases, the molar entropy also increases. This is because higher temperatures lead to greater molecular motion and disorder, resulting in higher entropy.
