Answer to Question #180680 in General Chemistry for En Hui Peng

Question

Calcium hydroxide and sulfuric acid react to produce calcium sulfate and water according to the equation:

Ca(OH)_2(aq)  +  H₂SO_4(aq)  --> CaSO_4(s)  +  2 H₂O_(l)

How many liters of 0.8 M Ca(OH)₂ are needed to produce 4.4 moles of CaSO₄?

Answer 1

Molar Mass of Ca(OH)₂ = 74.1 g/mol

Molar Mass of CaSO₄ = 136.14

Ratio = 1:1

4.4 moles of CaSO₄ = 4.4 moles of Ca(OH)₂

= 74.1 × 4.4

= 326.04 × 0.8 = 260.832 g

= 0.260832 L
