Question

Ppts 5. a) Balance the equation below. 4pts b) Calculate how many grams of calcium sulfat can aluminum sulfate based on the balanced equation. how many grams of calcium sulfat can be produced by reacting 2.16 moles of CaSO4(s) + Al(NO3)3 (aq) Ca(NO3)2 (aq) + Al(SO )) (aq) +

Answer 1

Solution:

A) The balanced equation will be written as,

3Ca(NO3)2(aq) + Al2(SO4)3(aq)$\rightarrow$3CaSO4 (s)+ 2Al (NO3)3(aq)

B) Mass of CaSO4 = 882.187 g

Calculation:

Since, 1 mol of Aluminium sulfate produces 3 moles of CaSO4

Hence, 2.16 mol will produces = 2.16 mol x 3 = 6.48 mol

Mass of CaSO4 = number of moles x molar mass

= 6.48 mol x 136.14 g mol-1 = 882.187 g
