how many molecules ## How many molecules does NH3?

The molar mass of NH3 is equalled to 17 gram. 0.5 moles of NH3 are present. 0.5×6.022×10^23 = 3.011×10^23 molecules of NH3. Each NH3 molecule has 4 atoms.

## How many molecules are in 25g of h2o?

[g/(g/mole) = moles]. Here we have 25.0 g/(18.0g/mole) = 1.39 moles water (3 sig figs). Multiply 1.39 moles times the definition of a mole to arrive at the actual number of water molecules: 1.39 (moles water) * 6.02 x 1023 molecules water/(mole water) = 8.36 x 1023 molecules water.Dec 19, 2020
