If you have 6.50 molar of chromium which is a molar mass of 52 grams what is the amount in grams of this amount of chromium?
You will have 6,5 times 52 grams = 338 grams
What is the difference between moles and equivalent moles?
The mole is the amount of substance, equal to molar mass of a compound or atomic weight of an element.The molar equivalent is the amount of substance which react with one mole of hydrogen.
What is a 1 molar solution?
Molar solution, commonly called molarity, is the amount of amount of substance in a certain volume. Typically it is measured in moles per litre. A 1 molar solution means there is one mole of substance per one litre. This can also be called a one mole concentration of solution.
Which of these solutions has the lowest concentration of NaCL a 0.25 b 0.5 c 1.0 d 1.5 and e 2.0 molar?
a) 0.25 molar is the smallest amount and thefore the lowest concentration of NaCl.
If an insufficient amount of a liquid unknown had been used how would this affect the value of the experimental molar mass?
When the unknown liquid is heated and turned into vapor, the unknown will not occupy the whole container. In the equation to find the molar mass (nRT)/PV, the volume will be greater than the actually volume of the unknown, thus leaving a molar mass that is less than the actual molar mass
What is the molar mass of sulfur?
The molar mass of sulfur is 32.065. Molar mass is the mass per mole of a substance. In other words, Molar Mass = Mass/Amount of Substance.
If you have 6.50 molar of chromium which is a molar mass of 52 grams what is the amount in grams of this amount of chromium?
You will have 6,5 times 52 grams = 338 grams
What is molar mass of iron?
The molar mass of iron is 55.845g per mol. Molar mass is the mass of a given substance divided by its amount of substance.
What is the difference between moles and equivalent moles?
The mole is the amount of substance, equal to molar mass of a compound or atomic weight of an element.The molar equivalent is the amount of substance which react with one mole of hydrogen.
How are molarity and molar mass related for a compound?
The molar mass of a substance is measured in grams per mole written as gmol-1. It is worked out using the Mole formula by dividing mass in grams by the amount in moles.
What is molar heat?
Different substances have varied molar heat capacities. The molar heat capacity of a substance refers to the amount of heat energy needed to raise 1 mole of that substance by 1 degree Celsius.
What is a 1 molar solution?
Molar solution, commonly called molarity, is the amount of amount of substance in a certain volume. Typically it is measured in moles per litre. A 1 molar solution means there is one mole of substance per one litre. This can also be called a one mole concentration of solution.
How does the molar concentration at Standard temperature and pressure depend upon the identity of the gas?
Molar concentration is defined as the amount of a gas divided by the volume of gas. According to the gas identity, at standard temperature and pressure, even if the amount of the gas is constant, the volume of gas changes. Thus, the molar concentration changes depending on the gas identity.
The amount of heat necessary to change 1 kg of a solid into a liquid at the same temperature is called the?
molar heat of fusion
Why are different masses of each element required to react with the same amount of hydrogen?
Each element has a different molar mass and Molarity, using stoichiometry the conversion of molar mass can explain why.
What is the difference between heat of reaction and molar heat of reaction?
Heat of a reacion is the totall amount of heat a reaction produces. Molar heat of a reaction is the heat produced/mol if you have the molar hear of the reaction you can calculate the heat of the reaction based on the moles of reactants you have
What information do the coefficients of a of a balanced equation give about the reactants?
These coefficients show the number of molecules (and the amount of substance) involved in the chemical reaction.
