Question

Sodium Phosphate reacts with calcium nitrate according to the following equation:

2 Na3PO4 + 3 Ca(NO3)2 - Ca3(PO4), + 6 NaNO3
-
If 49.33 grams of sodium phosphate reacts, how many grams of Calcium Phosphate is
produced?

Answer 1

Mass = 46.52 g

Step-by-step explanation:

Given data:

Mass of sodium phosphate react = 49.33 g

Mass of calcium phosphate produced = ?

Solution:

Chemical equation:

2Na₃PO₄ + 3Ca(NO₃)₂ → Ca₃(PO₄)₂ + 6NaNO₃

Number of moles of Na₃PO₄:

Number of moles = mass/molar mass

Number of moles = 49.33 g/ 163.94 g/mol

Number of moles = 0.300 mol

now we will compare the moles of Na₃PO₄ and Ca₃(PO₄)₂

Na₃PO₄ : Ca₃(PO₄)₂

2 : 1

0.300 : 1/2×0.300 = 0.15

Mass of Ca₃(PO₄)₂:

Mass = number of moles × molar mass

Mass = 0.15 mol × 310.14 g/mol

Mass = 46.52 g
