How many grams of calcium phosphate are produced if 800.0 mL of 4.25M Ca(OH)2 solution reacts with excess H3PO4

Balanced equation: 2H3PO4 + 3Ca(OH)2 - Ca3(PO4)2 + 6H2O

Question

How many grams of calcium phosphate are produced if 800.0 mL of 4.25M Ca(OH)2 solution reacts with excess H3PO4

Balanced equation: 2H3PO4 + 3Ca(OH)2 -> Ca3(PO4)2 + 6H2O

jfraser · Answer

turn the volume and concentration of calcium hydroxide into moles.

then use the molar ratio from the balanced reaction to find moles of calcium phosphate.

then turn the moles of calclium phosphate into grams using the molar mass of calcium phosphate
