A 5.00 L flask contains 7.94 g of a gas at STP. What is the molar mass of the gas? a 35.6 g/mol
b 179 g/mol
C 1.59 g/mol
d 14.1 g/mol

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2

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.
