Answer:</h3>
0.00106 mole
<h3>
Explanation:</h3>
- 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
