QUESTION 2How many moles are in 37.16 g of calcium sulfate,CaSO4

Sagot :

In order to find the number of moles in a given mass of any compound, we need to use the molar mass of this compound, which is the total mass present in 1 mol of the compound. The molar mass of CaSO4 is 136.14g/mol

136.14 grams = 1 mol of CaSO4

37.16 grams = x moles of CaSO4

136.14x = 37.16

x = 37.16/136.14

x = 0.27 moles of CaSO4

In 37.16 grams, we will have 0.27 moles of CaSO4
