To find the number of particles of
from 19.83g of
, we need to follow these steps:1. **Calculate the number of moles of
:** The molar mass of
is given as 32g/mol (since
has a molar mass of 16g/mol and
has two oxygen atoms).
2. **Convert moles to number of particles:** We use Avogadro's number, which is
particles/mol.
Therefore, the number of particles of
in 19.83g of
is
particles.The correct answer is:
