Question

6.02 x 10²⁰ molecules of urea are present in 100 mL of its solution. What is the concentration of this urea solution ?​

Answer 1

above answer is wrong

0.01M

please check

6.02×10^20 molecules contain

6.02×10^20/6.02×10^23 moles

=1 milli mole

concentration =number of moles/litre

=10^-3 (1 MILLI) / (0.1 L =100mL)

=10^-3×10=10^-2=0.01 M
