Nitrogen is a non metal element. Mass number of it is 14.
Calcium chloride with formula CaCl2 has molecular mass of 141. Commercial calcium chloride has formula CaCl2,2H2O.It's molecular mass is 177.
The formula of anhydrous calcium chloride is CaCl2, and its gram formula mass is 110.99. The gram atomic mass of calcium is 40.08. Therefore, the grams of calcium in 100 grams of calcium chloride is 100(40.08/110.99) or 36.11 grams, to the justified number of significant digits.
The formula mass of calcium acetate, CaC4H6O4, is 158.17g.mol−1
To find the formula weight you have to add each elements mass together. The formula for this compound is CaSO3. Ca:40.08 S:32.07 O:3X16=48 Total= 120.15 <---- this is the formula weight.
We can find calcium as a non metal element. Atomic number of it is 20.

The chemical formula for calcium phosphide is Ca3P2.Formula mass of Ca3P2 = 3(40.1)+2(31.0) = 182.3Amount of Ca3P2 = mass of sample / formula mass = 444/182.3 = 2.44mol
To find the formula weight you have to add each elements mass together. The formula for this compound is CaSO3. Ca:40.08 S:32.07 O:3X16=48 Total= 120.15 <---- this is the formula weight.
1. Calculate formula massCalcium carbonate has chemical formula CaCO3.Its formula mass is 40.1 + 12.0 + 3(16.0) = 100.12. Apply formula to calculate number of moles of CaCO3Amount of CaCO3= mass/formula mass= 50/100.1= 0.50mol
Calcium is a metal element. Atomic mass of it is 40.
For a partly ionically bonded compound such as calcium carbonate, the gram formula mass is substituted for a mole, which technically exists only for purely covalently bonded compounds. The gram formula mass for calcium carbonate is 100.09. Therefore, 200 grams constitutes 200/100.09 or 2.00 gram formula masses of calcium carbonate, to the justified number of significant digits.
