Calculate the mass of 1 u in grams.​

Answer 1

Q. Calculate the mass of 1 u in grams.

$ans = 1.66 \times {10}^{ - 24}g$

Explanation:-

$1u = \frac{1}{12} mass \: of \: th e \: carbon \: atom$

$then \: mass \: of \: carbon \: atom$

$6.022 \times {10}^{23} atoms \: of \: carbon \: weight \: = 12g$

$mass \: of \: 1 \: carbon \: atom \: = \frac{12}{6.022 \times {10}^{23} }$

$= 1.99 \times {10}^{ - 23} g$

Therefore,

$1u = \frac{1}{12} \times 1.99 \times {10}^{ - 23} g$

$= 1.66 \times {10}^{24} g$
