Respuesta :

0.02 g of calcium carbonate (CaCO₃)

Explanation:

To solve the question we use the Avogadro's number using the following reasoning:

if         1 moles of calcium carbonate contains 6.022 × 10²³ units of calcium carbonate

then   X moles of calcium carbonate contains 12.044 × 10²³ units of calcium carbonate

X = (1 ×  12.044 × 10²³) / 6.022 × 10²³ = 2 moles of calcium carbonate

mass = number of moles × molecular weight

mass of calcium carbonate (CaCO₃) = 2 / 100 = 0.02 g
