Question

Calculate the number of moles of calcium chloride Cacl2 that can be obtained from 25g of limestone CaCo3 in the presence of excess hydrogen chloride

Answer 1

same as moles of CaCO3

CaCO3 = 100 g/mol = 40 + 12 + 48
so we have 0.25 mols of lime and will get 0.25 mols of CaCl2

Answer 2

0.25 moles of cacl2 as:
CaCo3+ HCl = CaCl2 + H2CO3
SO 1 mol of CaCO3 will give 1 mol of CaCl2.
mass of CaCO3= 25g
Molar mass of CaCO3= 100g
therefore moles of CaCO3 = 25/100 =0.25
thus 0.25 moles of CaCl2 will be produced
