Question

6.02×10^20 molecules of urea are present in 100ml of its solution. What will be the concentration?

Answer 1

number of moles of urea = molecules of urea present/ avagadro number
=6.02x10^20/6.02x10^23
=10^-3 moles
concentration = number of moles / volume of solution
=10^-3/(100x10^-3)(since it in ml)
=10^-2
therefore the final answer
concentration is 10^-2M (molarity)

if u like my explanation
give me brianliest.

thank you.
