1 mole of any substance is: 6.022*10²³ atoms or molecules.
9 moles of H₂S=9(6.022*10²³ molecules)=5.4198*10²⁴ molecules.
answer:there are 5.4198*10²⁴ molecules in 9.00 moles of H₂S.
Your answer is A. Weathered rocks and decomposed organic remains.
Answer: 1.80g
Explanation:
Molar Mass of AlCl3 = 27 + (3x35.5)
= 27 + 106.5 = 133.5g/mol
Number of mole of AlCl3 = 0.0135mol
Mass = 0.0135 x 133.5= 1.80g
