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

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.

answer:   you might love summer weather, but you don’t want it to feel like the sun is inside your car. but a hot car that just won’t seem to cool down might be a bigger of a problem than you think. your car relies on being at the right temperature.
