How many moles of water are
in 1.23x1018 water molecules?
[? ]x10'?)

There are 2,04x10 e-6 moles of water in 1.23x10e18   molecules

Explanation:

We use Avogadro's number, according to which in 1 mole of any substance there are 6,023 x 10 e23 particles (example: atoms, molecules). We calculate the number of moles according to the following simple three rule:

6,023 x 10 e23 molecules1 mol of water

1.23x10e18   moleculesx=

x=(1.23x10e18   molecules x1 mol of water)/6,023 x 10 e23 molecules

x=2,04x10 e-6 moles of water

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
