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.
