The molar mass of sucrose (c12h22o11) is 342.3 g/mol. a chemist has a 0.500-mol sample of sucrose. what is the mass, in grams, of this sample? 171 342 500 684

The mass of the sucrose is 171 g

Solution:

The molar mass of sucrose () is 342.3 g/mol

Moles of sucrose  = 0.500 moles

Mass of the sucrose :

Hence, the mass of the sucrose is 171 g.

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.
