How many molecules are there in 5.0 g of methyl alcohol, ch3oh?

molecules

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number of particles.

To calculate the number of moles, we use the equation:

given mass of methyl alcohol = 5.0 g

Molar mass of methyl alcohol = 32.04 g/mol

Putting in the values we get:

1 mole of methyl alcohol contains=6.022\times 10^{23}[/tex] molecules

Thus 0.16 moles of methyl alcohol contain=

molecules

Thus there are molecules in 5.0 g of methyl alcohol.

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.
