Question

calculate the number of atoms in 0.05 gram of water ?​

Answer 1

Answer:

We know that 18 grams of water contain 6.022 x $10^{23}$ atoms

So, the number of atoms in 0.05 grams of water can be found out by dividing the given amount by 18 and then multiplying it with the Avogadro number

So,

$\frac{0.05}{18}$ x 6.022 x $10^{23}$

After calculation, we get 1.672 x $10^{21}$ atoms
