There are molecules of water are in 345 grams.

Explanation:

Where:

m = mass of compound

M = Molar mass of compound

N = Number of particles / atoms/ molecules

n = Number of moles

= Avogadro's number

Mass of water = m =  345 g

Molar mas of water = M = 18 g/mol

Number of molecules of water = N

There are molecules of water are in 345 grams.
