A calcium sulfate crystal weighing 0.150 grams contains 0.00523 moles of oxygen.
White crystalline calcium sulfate, or CaSO4, is a material. Calcium sulphate is hydrate in the mineral or natural substance known as gypsum. As a food additive, calcium sulfate serves as a thickener, anti-caking agent, dough conditioner, dough strengthener, flour treatment agent, and yeast food. It is a thin, odorless powder that is white or white yellow.
Crystallized calcium sulfate mass = m = 0.150 g
Crystallized calcium sulfate's molecular mass is M = 172 g/mol.
Magnesium nitrate moles are equal to n=0.150/172 g/mol = 0.000872 mol.
6 moles of oxygen atoms make up 1 mole of the calcium sulfate crystal. The calcium sulfate crystal will then have 0.004446 moles.
A calcium sulfate crystal weighing 0.150 grams contains 0.00523 moles of oxygen.
