15.00g of glucose is added to 250g of water at 293 k. if the vapour pressure of water at 293k is 17.535 mmHg. Calculate the lowering of vapour pressure at 293k.

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.
