Convert 236 mg MgP207 to moles. Use three significant figures in your answer.

0.00106 mole

Explanation: The number of moles of a compound is calculated by dividing the mass of the compound by its molar mass.

Assuming the formula of the compound given is Mg₂P₂O₇ (magnesium pyrophosphate)

Molar mass of Mg₂P₂O₇ = 222.55 g/mol

Mass of the compound = 236 mg or 0.236 g

Therefore;

Number of moles = 0.236 g : 222.55 g/mol

= 0.0010604

= 0.00106 mole (3 sf)

Therefore, the number of moles of Mg₂P₂O₇ are 0.00106 mole
