Question

density of water is 1 gram per ml. calculate the number of molecules present in 1 litre water​

Answer 1

Answer:

density= m/v

1g/ml = m/1000ml (1L=1000ml)

m = 1000g

we know the formula...

moles=wt./M wt.

moles=1000/18

moles=55.5

so no. of molecules=molesxNA

molecules=55.5x6.022x10^23

molecules=3.34x10^25
