Question

In 90gm water how many atom are there​

Answer 1

Answer:

9.03×10²⁴

Explanation:

m=90g

molar mass = 18g/mol

no of molecules=mass/molar mass×avogadro number

no of molecules=90/18×6.022×10²³

=5×6.022×10²³

=30.01×10²³

=3.01×10²⁴

1 molecule of water has atoms=3

3.01×10²⁴molecules of water has atoms

=3×3.01×10²⁴

=9.03×10²⁴
