# Number of atoms in 0.01 mol of NH3 watch

What I'm doing is, (6.022*10"23) * (0.01) and its wrong, i don't get how to do it. Pls help.
2. You calculated the number of NH3 particles, now multiply by 4 for number of atoms, as 1 ammonia molecule has 4 atoms.

There are 4 atoms in NH3, so (4xAvagadro)x0.01

Avogadro's number is how many NH3 molecules you'll find in 1 mole of substance, so you'd factor it down by 100 since 0.01 is 1/100th of 1
Then I'd assume you just multiply that number by 4, (since there are 4 atoms in ammoia but not entirely certain)
