mol = mass/Mr
If the Mr and number of moles of a substance is known then the mass can be calculated.
example:-
if we have 1 mole of Na, how many grams do we have?
mass = mol x Mr
mass = 1 x 23
mass = 23g

What is 2.20 moles of Sn converted into mass grams?
The number 2.20 moles of Sn equals 261.14 grams. This is a taught in biology.
How many grams are in 5.2 moles of magnesium sulfide?
Mass in grams = no of moles x molecular mass. So, mass in grams = 5.2x 56 = 291.2g
Formula for moles?
number of moles = mass of the material/molar mass
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 is the mass in grams of 5.40 moles of helium?
For this you need the atomic mass of He. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.5.40 moles He × (4.00 grams) = 21.6 grams He
What is 2.20 moles of Sn converted into mass grams?
The number 2.20 moles of Sn equals 261.14 grams. This is a taught in biology.
How is the mass in grams of an element converted to amount in moles?
1 mol of any element is the atomic weight expressed in grams.
Convert 1.3 moles of calcium to grams?
52.1grams. moles = mass (in grams)/RMM (relative molecular mass) 1.3 moles = mass (in grams)/ 40.078 mass = 40.078 x 1.3 = 52.1grams
How many moles of barium are present in a sample having a mass of 22.3 grams?
# of moles = grams of substance / molar mass of substance molar mass of Barium =137.33 grams/mole #moles of Barium = 22.3 grams/ 137.33 grams/mole = 0.162382582 moles
How is the mass in grams of an element converted to the amount of moles?
The formula is number of moles = mass / molecular mass. So say we have 1 mole of water. We look at the periodic table and molecular mass is 1+1+16 = 18g/mol. 1 mole x 18g/mol is 18 grams.
How many grams are in 5.2 moles of magnesium sulfide?
Mass in grams = no of moles x molecular mass. So, mass in grams = 5.2x 56 = 291.2g
Formula for moles?
number of moles = mass of the material/molar mass
How many moles are in 89.0 grams of aluminum?
all you have to do to fine the moles of any element is divide the given grams by the molar mass (which you can find on a periodic table of elements) Likewise, if you need to find the grams, just multiply the number of moles by molar mass. moles = grams/molar mass grams = moles x molar mass your equation should look like this: moles = 89.0 / 17.0 moles = .471
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.
How many moles are in 57 grams of Xenon?
To find the number of moles in 57 grams of Xenon, divide the given mass (in grams) by the molar mass of Xenon. The molar mass of Xenon is 131.3 grams/mol. Therefore, 57 grams of Xenon is equal to 0.434 moles (57/131.3).
Mass of 3 moles of ammonia would be?
The molar mass of ammonia is about 17 grams, so that 3 moles would have a mass of 51 grams.
What is the Mass in Grams of 1.50 moles of hydrogen peroxide?
The molar mass of hydrogen peroxide is about 34; therefore, 1.5 moles has a mass of about 51 grams.
