Answer:

0.88mol

Explanation:

The number of moles, n, contained in a substance can be calculated using the formula;

Moles (n) = mass (m) ÷ molar mass (MM)

Molar mass of Magnesium oxide (MgO) = 24 + 16

= 40g/mol

According to the question, Mass of MgO = 35grams

Mole = 35/40

Mole = 0.875

Mole = 0.88mol
