How many representative particles are in 1.45 g of a molecular compound with a molar mass of 237 g?
1.45 g of a molecular compound with a molar mass of 237 represents 1.45/237 or 6.118 X 10-3 mole. Assuming that "representative particles" in the question means "molecules", this is (6.118 X 10-3){Avogadro's Number} or 3.68 X 1021 molecules.
How many representative particles are in 1.45 g of a molecular compound with a molar mass of 237g?
There are 1,45/237 = 0,00612 moles of the compound. Multiplying this amount of substance with Avogadro's number gives us the number of residing molecules: 0,00612 x 6,022*1023 = 3,68*1021 particles.
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 three conversion factors are oftem used in mole conversion?
Three common conversion factors used in mole conversions are Avogadro's number (6.022 x 10²³ particles/mole), which relates moles to the number of atoms or molecules; the molar mass (grams/mole) of a substance, which converts between grams and moles; and the ideal gas law, where 1 mole of an ideal gas occupies 22.4 liters at standard temperature and pressure (STP). These factors facilitate conversions between different units when dealing with chemical quantities.
What is the relationship between the molar enthalpy of fusion of a solid and the strength of attraction between that solids particles?
The molar enthalpy of fusion is a measure of the energy required to break the intermolecular forces holding the particles together in a solid. A higher enthalpy of fusion indicates stronger intermolecular forces between particles, which suggests a stronger attraction between the solid's particles.
How do you convert from number of particles to moles?
You must first calculate the molar mass of the substance. To do so, you add up the molar masses of all the elements that make up the compound, multiplied by the number of atoms of that element in one molecule of the substance. For example, AgNO3 has a molar mass of about 169.8 amu. In one molecule of AgNo3, there is one atom of Silver (molar mass 107.8), one atom of Nitrogen (molar mass 14), and three atoms of Oxygen (molar mass 16). Multiply the molar mass of Silver by the number of Silver atoms (1), multiply the molar mass of Nitrogen by the number of Nitrogen atoms (1), multiply the molar mass of Oxygen by the number of Oxygen atoms (3), add the numbers up and you have the molar mass of the substance (169.8). Step 2 is easy. To convert from grams to moles, you divide the number of grams by the molar mass (units for molar mass are grams per mole, so dividing by molar mass cancels the grams). To convert from moles to grams, you multiply by the molar mass.
How many representative particles are in 4.51 g of a molecular compound with a molar mass of 273 grams?
4.51 g x 1 mol x 6.022 x 1023 molecules = 9.95 x 1021 molecules .............273 g ............... 1 mol
How many particles make up 1 molar solution?
6.023 X 1023 particles make up a 1M solution.
What is the difference between a mole and a molar in chemistry?
In chemistry, a mole is a unit of measurement used to express the amount of a substance, while a molar is a term used to describe the concentration of a substance in a solution. A mole represents a specific number of particles (6.022 x 1023) of a substance, while molar refers to the amount of a substance dissolved in a liter of solution.
How many moles of specified particles are present in a sample of N'O if each sample weighs 7.00 g?
To calculate the number of moles of particles present in a sample, you need to divide the sample's mass by the molar mass of the particles. If you specify the particles as N'O, you should provide the molar mass of N'O for an accurate calculation.
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.
