Question

Find the molecular mass of H2O?​

Answer 1

Answer:

Molecular mass of H2O is 16

Explanation:

2×1 + 1×16 = 18

Answer 2

$\large \bold{ \underline{ \underline{ \: \sf Answer : \: \: \: }}}$

$\to$ 18 u

$\large \bold{ \underline{ \underline{ \: \sf Explaination : \: \: \: }}}$

$\star$ Atomic mass of hydrogen = 1 u

$\star$ Atomic mass of oxygen = 16 u

$\underline{ \sf \: Molecular \: mass \: of \: H2O : \: \: }$

$\to$ ( 1 × 2 ) + 16

$\to$ 2 + 16

$\to$ 18

Hence , the molecular mass of H2O is 18
