Question

How many atoms are in 1 gram of water​

Answer 1

Explanation:

Thus, there are 3.35 * 10^22 molecules of water in 1 gram. Now, each molecule of water has 2 hydrogen atoms and 1 oxygen atom. This means that there are 3 atoms in each molecule.

Answer 2

Answer:

Actually answer is

$\frac{1}{18} \times 6.022 \times{10}^{23} \times 3$

Answer

$1.0036 \times {10}^{23}$

The reason of multiplying 3 is because you ask the no. of atom not the number of molecule.

The number of molecule formula is

$\frac{given \: mass}{atomic \: mass \: of \: a \: molecule} \times avagadro$

But you asked for number of atoms so we have to multiply by number of atom in molecule also

example :- H2O have 3 atom

Co2 have also 3 atom.

Hope it's helps
