The chemical formula for calcium phosphide is Ca3P2.
Formula mass of Ca3P2 = 3(40.1)+2(31.0) = 182.3
Amount of Ca3P2 = mass of sample / formula mass = 444/182.3 = 2.44mol

What is Ca3P3?
Ca3P3 is the chemical formula for calcium phosphide, a compound composed of calcium and phosphorus. It is often used as a pesticide and a rodenticide due to its toxic properties. Calcium phosphide reacts with water or moisture to produce phosphine gas, which is highly toxic to many organisms.
How many grams are in 2.8 moles of calcium carbonate?
The molar mass of calcium carbonate (CaCO3) is 100.09 g/mol. Therefore, 2.8 moles of calcium carbonate would be 280.25 grams.
How many moles of calcium are in a sample of 40 g?
There are approximately 1 mole of calcium in 40 g, as the molar mass of calcium is about 40 g/mol.
How many moles of calcium is 126g of ca?
To find the number of moles in 126g of calcium, divide the given mass by the molar mass of calcium (40.08 g/mol). 126g Ca / 40.08 g/mol = 3.14 moles of Ca.
How many moles are in 3.75 grams of calcium?
To find the number of moles in 3.75 grams of calcium, divide the mass of calcium by its molar mass. The molar mass of calcium is approximately 40.08 g/mol. Therefore, 3.75 grams of calcium is equal to 0.0936 moles.

How many grams of phosphorus are in 500 grams of calcium phosphide?
To find the grams of phosphorus in calcium phosphide, first find the molar mass of calcium phosphide (Ca3P2 = 3Ca + 2P = 340.08 + 230.97 = 276.42 g/mol), then calculate the mass percent of phosphorus in calcium phosphide (2P/276.42 g/mol * 100%). Finally, determine the grams of phosphorus in 500 grams of calcium phosphide by multiplying the mass percent by 500 grams.
