What conversion factor is used when converting moles to mass?
the molar mass 1 mole = xxx grams based on the chemical formula Ex: CO2 ... the atomic mass of carbon is 12, and the atomic mass of oxygen is 16 but the molar mass = (1 x 12) + (2 x 16) because of the number of atoms of each in the formula. molar mass = 44. so 1 mole = 44 grams ... turn this fact into a conversion factor. 44g / 1mole is the conversion factor to convert moles of carbon dioxide into mass (grams). Each substance will have a different molar mass, so a different conversion factor.
Is molar mass the conversion factor in stoichiometry?
Yes - it allows one to convert the stoichiometric ratios into mass ratios.
How is the number of moles of an element determined froma known mass?
the molar mass is used as a conversion factor to convert grams to moles
How many grams of Cl in 5.00 g of PbCl2?
you start with the 5.00g PbCl2 then use a conversion factor for the molar mass of pbcl2 (1mol pbcl2/278.1gpbcl2) now from mol pbcl2 use another conversion factor to get g cl2 (70.90gCl2/1 mol PbCl2) do the math and you wind up with 1.27 g Cl2
The mass of a mole of a substance expressed in grams is called a?
molacular mass

How is the number of moles of an element determined froma known mass?
the molar mass is used as a conversion factor to convert grams to moles
Which mathematical relationship should you use to convert moles of a substance into grams?
Multiplication by what is called a conversion factor. A moles x (bbb grams / 1 mole) in which bbb is the molar mass of the substance.
Convert grams to moles?
Conversion of a certain mass of a substance to moles requires knowing the molar mass. Molar mass is given in grams per mole. Dividing the known mass by the molar mass gives the number of moles.
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.
How do you convert from moles of one material to another?
Each compound has a specific molar mass; no conversion.
What quantity serves as the conversion factor between the mass of a sample and how many moles the sample contains?
The quantity that serves as a conversion factor between mass and number of moles is the molecular mass.
What are the steps required to find the mass of an element from a given amount of the element in moles?
The mass of 1 mole of the element is used as conversion factor to covert grams to moles. ~APEX
How many grams of Cl in 5.00 g of PbCl2?
you start with the 5.00g PbCl2 then use a conversion factor for the molar mass of pbcl2 (1mol pbcl2/278.1gpbcl2) now from mol pbcl2 use another conversion factor to get g cl2 (70.90gCl2/1 mol PbCl2) do the math and you wind up with 1.27 g Cl2
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.
The mass of a mole of a substance expressed in grams is called a?
molacular mass
