Not 100% sure but I think it’s Nucleic acid
Answer: 2.43 x 10^23 molecules
Explanation:
Molar mass of H2S: 2(1.008) + 32.06 = 34.1 g/mole
Avogadro’s number for converting moles to atoms or molecules: 6.02 x 10^23
(13.751375g H2S)(1 mole H2S)(6.02x10^23 molecules) / (34.1g/mole H2S)(1mole H2S) = 2.43 x 10^23 molecules H2S
