What is the mass in gram of 1 atom of an element if its atomic mass is $10 \mathrm{u}$ ?
What is the mass in gram of 1 atom of an element if its atomic mass is $10 \mathrm{u}$ ?
$2.06056 \times 10^{-22} \mathrm{~g}$
$1.66056 \times 10^{-23} \mathrm{~g}$
$1.06056 \times 10^{-24} \mathrm{~g}$
$3.66056 \times 10^{-25} \mathrm{~g}$
Solution
Atomic mass is the mass of an atom of the element.
Mass of 1 atom of the element $=10 \mathrm{u}$
Now, $1 \mathrm{u}=1.66056 \times 10^{-24} \mathrm{~g}$
Therefore, $10 \mathrm{u}=1.66056 \times 10^{-23} \mathrm{~g}$
