Answer:
B
Explanation:
The ratios of the coefficient of the compounds in a balanced chemical equation tells us the relationship of each compound to the others in terms of mole.
Based on the equation,
3 moles of CO₂ would require 2 moles of phosphoric acid.
3 mol CO₂ ------- 2 mol H₃PO₄
1.5 mol CO₂ ------- 2 ÷2= 1 mol H₃PO₄
Or 1.5 mol would require mol of H₃PO₄
To find mass of H₃PO₄, multiply the number of moles by its Mr, which can be deduced with the help of the periodic table.
Ar of H₃PO₄
= 3(Ar of H) + Ar of P +4(Ar of O)
= 3(1) +31 +4(16)
= 98
Multiply 98 with the number of moles, 1, to obtain the answer.
So if you would look at the steps above, here's what we did:
