Question

Number of moles of water in $1$ litre of water with density $1g/cc$ are:

• A. $55.56$
• B. $45.56$
• C. $56.55$
• D. $56.45$

Answer 1

The correct option is A $55.56$

Given that

volume of water=$1L=1000cc=1000g$

Density of water=$1g/cc$

mass of $1$ mole of watre is $18$ g

Hence the number of moles

$\frac{1000}{15}=55.55moles$
