Question
What will be mass of one ${ }^{12} C$ atom in g ?
✓
Answer
1 Mole ${ }^{12} C$ atom $=6.022 \times 10^{23} C$ atom
$=12 g$ Carbon (molar mass of C )
Hence mass of 1 atom of $=\frac{12 g}{6.022 \times 10^{23}}$
$=1.99269 \times 10^{-23} g$
$=12 g$ Carbon (molar mass of C )
Hence mass of 1 atom of $=\frac{12 g}{6.022 \times 10^{23}}$
$=1.99269 \times 10^{-23} g$
