Question

One atomic mass unit is equivalent to

• A. $1.67\times {10}^{-27}g$
• B. $1.66\times {10}^{-27}kg$
• C. $1.67\times {10}^{-27}mg$
• D. $1.6\times {10}^{-24}g$

Answer 1

Answer: (B), (D)

$1.66\times {10}^{-27}kg$
$1.6\times {10}^{-24}g$

One amu $=\frac{1}{N_A}=\frac{1}{6.02\times {10}^{23}}$

$=1.66\times {10}^{-24}g=1.66\times {10}^{-27}kg$

So, the correct options are $B$ and $D$
