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
