How many moles of h 3 po 4 are produced when 71.0 g p 4 o 10 reacts completely to form h 3 po 4

It will be produced 1 mol of H₃PO₄

Explanation:

The reaction is this one:

P₄O₁₀  +  6H₂O  →  4H₃PO₄

Molar mass of P₄O₁₀  = 283.88 g/m

Mol = Mass / Molar mass

Mol = 71 g / 283.88 g/m = 0.250 mol of P₄O₁₀

Ratio is 1:4 so 1 mol of P₄O₁₀ will produce 4 moles of phosphoric in the reaction.

0.250 mol of P₄O₁₀ will produce 1 mol of H₃PO₄  (0.250 .4)

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
