Question

Which of the following expressions is correct (n = no. of moles of the gas, N${}_A$ = Avogadro constant, m = mass of $1$ molecule of the gas, N = no. of molecules of the gas)?

• A. n = mN${}_A$
• B. m = N${}_A$
• C. N = nN${}_A$
• D. m = n/N${}_A$

Answer 1

The correct option is C N = nN${}_A$

As we know, $N=n\times N_A$.
