Question

The mass of magnesium that contains the same number of atoms as are present in 2g of calcium is:

Answer 1

Explanation:

Molar mass of Calcium = M' = 40

Molar mass of the Magnesium = M = 24

Gn:

Mass of Calcium = m' = 8g

Mass of Magnesium = m = ?.

Formula:

m = m' × M' / M

m = 8 × 24 / 40

= 4.8g

[ m = 4.8 g ]
