MCQ
The number of molecules in $16\,gm$ of methane is
- A$3.0 \times {10^{23}}$
- ✓$6.02 \times {10^{23}}$
- C$\frac{{16}}{{6.02}} \times {10^{23}}$
- D$\frac{{16}}{{3.0}} \times {10^{23}}$
✓
Answer
Correct option: B.
$6.02 \times {10^{23}}$
b
Given $16 \,g$ Methane $\left( CH _4\right)$
Given $16 \,g$ Methane $\left( CH _4\right)$
molar mass $=16$
Moles of $CH _4=\frac{16}{16}=1$
$1$ moles $=6.02 \times 10^{23}$ molecules
