Answer: 1.66x10 +4 moles of NH3
Explanation: To find the number of moles just divide the given value of molecules to the Avogadro's number.
Solution: 9.97x10 +19 molecules NH3 X 1 mole NH3 / 6.022X10+23
Answer:
604.11
Explanation:
1 mole = 6.023 × 10^23 (avogadros constant)
6.023 × 10^23 ÷ 9.97 × 10^19
