How many particles are in 1.43 g of a compound with a molar mass of 233? (No molar mass calculation needed) (show work plz)

Explanation:

mol = given mols / molar mass

given mass = 1.43 grams

molar mass = 233

mols = 1.43 / 233 = 0.00614

1 mol contains 6.02 * 10^23 particles

0.00614 moles = x                                  Cross multiply

1*x = 0.00614 * 6.02*10^23

x = 3,68 * 10^21 particles.

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.
