Question

what is the mass of 0.35 of caco3

Answer 1

Answer:

35 g/mol

Explanation:

The. atomic mass of carbon=12

oxygen=16 calcium =40

The molecular mass of CaCO3 = 40+12+16*3 = 100.

This means that,the avogadro's number (=6.022 * 10^23) of CaCO3 molecules ,then the mass will be 100 grams. so 100 * 0.35=35
