For this you need the atomic (molecular) mass of CaSO4. Take the number of grams and divide it by the Atomic Mass. Multiply by one mole for units to cancel. CaSO4= 136.2 grams
54.0 grams Ca / (136.2 grams) = .396 moles Ca

How many atoms are in 187 grams of calcium?
To find the number of atoms in 187 grams of calcium, we first need to determine the number of moles of calcium. This is done by dividing the mass (in grams) by the molar mass of calcium (40.08 g/mol). Next, we can use Avogadro's number (6.022 x 10^23 atoms/mol) to calculate the number of atoms in that number of moles.
What mass of nitrogen in grams is present in 148 grams of ammonium sulfate?
Ammonium sulfate contains 21% nitrogen by mass. To find the mass of nitrogen in 148 grams of ammonium sulfate, you would first calculate 21% of 148 grams, which equals 31.08 grams of nitrogen.
How many atoms of chloride are in 654.5 grams of calcium chloride?
To find the number of chloride atoms in 654.5 grams of calcium chloride, you would first calculate the number of moles of calcium chloride using its molar mass. Then, since each formula unit of calcium chloride contains two chloride ions, you would multiply the number of moles by 2 to find the number of chloride atoms.
How many moles of calcium is in 80 grams?

How many grams of calcium in 418 grams of Ca CO 3?
There are 40.08 grams of calcium in 100 grams of CaCO3. To find the amount of calcium in 418 grams of CaCO3, you can set up a proportion and calculate that there are approximately 167.2 grams of calcium in 418 grams of CaCO3.
How many grams of calcium sulfate are there in two moles?
Calcium sulfate has chemical formula CaSO4. The formula mass is 40.1+32.1+4(16.0) = 136.2Mass of 2mol of CaSO4 = 2 x 136.2 = 272.4gThere are 272.4 grams of calcium sulfate in a two mole sample.
Mass in grams if the molar mass of sodium sulfate is 141.98 gramsmoles?
To calculate the mass in grams of sodium sulfate, we need to know the number of moles. Once we have the number of moles, we can multiply it by the molar mass to find the mass in grams. For example, if we have 2 moles of sodium sulfate, the mass would be 2 moles * 141.98 grams/mole = 283.96 grams.
How many tablespoons is 20 grams of calcium sulfate?
The density of calcium sulfate dihydrate powder is 4.2g/tbsp, so 20g would be 20/4.2 = 4.8tbsp.
How many atoms are in 187 grams of calcium?
To find the number of atoms in 187 grams of calcium, we first need to determine the number of moles of calcium. This is done by dividing the mass (in grams) by the molar mass of calcium (40.08 g/mol). Next, we can use Avogadro's number (6.022 x 10^23 atoms/mol) to calculate the number of atoms in that number of moles.
What is the mass in grams of 1.15 mol of strontium sulfate?
To find the mass of 1.15 mol of strontium sulfate, you first need to calculate the molar mass of strontium sulfate, which is 183.68 g/mol. Then, multiply the molar mass by the number of moles: 1.15 mol * 183.68 g/mol = 211.22 grams. Therefore, the mass of 1.15 mol of strontium sulfate is 211.22 grams.
How many atoms are in 165 grams of calcium?
To calculate the number of atoms in 165 grams of calcium, you need to first determine the number of moles using the molar mass of calcium. Calcium has a molar mass of approximately 40.08 g/mol. Once you have the number of moles, you can use Avogadro's number (6.022 x 10^23) to convert moles to atoms.
What mass of nitrogen in grams is present in 148 grams of ammonium sulfate?
Ammonium sulfate contains 21% nitrogen by mass. To find the mass of nitrogen in 148 grams of ammonium sulfate, you would first calculate 21% of 148 grams, which equals 31.08 grams of nitrogen.
How many atoms are in 40.08 grams of calcium?
To find the number of atoms in 40.08 grams of calcium, you first need to determine the number of moles using the molar mass of calcium (40.08 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to calculate the number of atoms. In this case, 40.08 grams of calcium would contain 1 mole of calcium atoms, which is equal to 6.022 x 10^23 atoms.
How many grams of lithium nitrate will be needed to make 250 grams of lithium sulfate assuming that you have an adequate amount of lead sulfate to do the reaction?
To determine the number of grams of lithium nitrate needed to make 250 grams of lithium sulfate, you need to calculate the molar mass of lithium sulfate and lithium nitrate, then use stoichiometry to find the ratio of lithium nitrate to lithium sulfate. Finally, apply this ratio to find the mass of lithium nitrate needed for the reaction. Lead sulfate is not involved in this calculation as it is not part of the reaction between lithium nitrate and lithium sulfate.
