Water has a mass per mole of 18.0 g/mol, and each water molecule (h20) has 10 electrons. (a) how many electrons are there in one liter (1.00 x 10 m ) of water?

total number of electron in 1 litter is 3.34 × electron

Explanation:

given data

mass per mole = 18 g/mol

no of electron = 10

to find out

how many electron in 1 liter of water

solution

we know molecules per gram mole is 6.02 × molecules

no of moles is 1

so

total number of electron in water is = no of electron ×molecules per gram mole × no of moles

total number of electron in water is = 10 × 6.02 × × 1

total number of electron in water is = 6.02× electron

and

we know

mass = density × volume    ..........1

here we know density of water is 1000 kg/m

and volume = 1 litter = 1 × m³

mass of 1 litter = 1000 × 1 ×

mass = 1000 g

so

total number of electron in 1 litter =  mass of 1 litter ×

total number of electron in 1 litter =  1000 ×

total number of electron in 1 litter is 3.34 × electron
