Question

3.40mol P2O5 to grams P2O5

Answer 1

Answer:

482.596 grams

Explanation:

The relationship between moles, molar mass and mass of a compound is given by;

$Moles =\frac{mass}{molar mass}$

In this case;

The compound in question is P₂O₅

Molar mass of P₂O₅ =  141.94 g/mol

Rearranging the formula;

Mass = Moles × molar mass

Therefore;

Mass of P₂O₅ = 3.4  mol ×  141.94 g/mol

                       =  482.596 grams

Therefore, mass of P₂O₅ is  482.596 grams
