Question

If one mole of carbon atom weight 12 kg. What is the mass (in grams) of 1 atom of carbon ??

Answer 1

1 mole = 6.022 × 10^23 atoms.

1 atom =
$\frac{1}{6.022 \times 10 {}^{23} }$
given mass = 12 g
so number of atoms =
$12 \times \frac{1}{6.022 \times {10}^{23} } = \frac{1.99}{ {10}^{23} }$
now to convert it into whole number we have
$\frac{1.99}{10 {}^{23} } = 1.99 \times {10}^{ - 23}$
hope it helps

Answer 2

HEYA..

HERE IS YOUR ANSWER...

GIVEN-

MASS OF CARBON - 1 g

MOLECULAR MASS OF HYDROGEN IS - 12 g

MASS/ MOLECUAR MASS = MOLE

THEREFORE MASS OF 1g OF CARBON ATOM= 1/12 * MOLE

[OR]

1/12 * 6.22*10^23
