Answer:
0.0526mol
Explanation:
The chemical equation given in this equation is as follows:
Na3PO4 + Sr(NO3)2 → Sr3(PO4)2 + NaNO3
However, this equation is unbalanced as the number of atoms of each element on each side does not correlate. The balanced equation is as follows:
2Na3PO4 + 3Sr(NO3)2 → Sr3(PO4)2 + 6NaNO3
This balanced equation means that:
2 moles of Sodium Phosphate (Na3PO4) is required to react with 3 moles of Strontium Nitrate (Sr(NO3)2)
Hence, if 0.0789 moles of Strontium Nitrate are reacted, then 0.0789 × 2/3
moles of sodium phosphate will also react.
= 0.0789 × 2/3
= 0.1578/3
= 0.0526mol
