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.

Where does the mole ratio between two chemicals come from?
Mole ratio is the number of moles of a substance divided by the total number of moles of all substances present, times 100.
Why cant molar mass be used as a conversion factor?
It can be used as a conversion factor.
What is the mass of 11 moles of KCl?
The atomic mass of potassium is 39 The atomic mass of chlorine is 35.5 The formula mass of KCl is the sumof these. This is the mass in grams of one mole of KCl. Use this as a conversion factor to find mass of 11 moles
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.
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
What conversion does the value of the conversion factor depend upon the formula of the substance?
mass of any substance to moles
How is the number of moles of an element determine from a known mass?
The mass of 1 mole of the element is used as a conversion factor to convert grams to moles
What is the difference between converting amounts in moles to mass and converting mass to amounts in moles?
There are only two reverse operations.
What conversion factor for sodium is used to change mass to moles is?
2.54 times 10 to the 23 power
Where does the mole ratio between two chemicals come from?
Mole ratio is the number of moles of a substance divided by the total number of moles of all substances present, times 100.
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.
Why cant molar mass be used as a conversion factor?
It can be used as a conversion factor.
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.
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 do you convert from moles of one material to another?
Each compound has a specific molar mass; no conversion.
