Question

Calculate the number of moles in Caco3 & H@so4? [5mark]

Answer 1

1 moles

The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles CaCO3, or 100.0869 grams.

Answer 2

Answer:

1mol Caco3=100 g Caco3

1mol H@so4=98.016 g H@so4

Explanation:

mass of Ca=40,C=12, O=16,S=32, H=1.008

1mol Caco3=20+12+16×3=100 g Caco3

1 mol H@so4=1.008×2+32+16×4=98.016 g H@so4
