Answer:
Number of hydrogen sulfide molecule = 5.7672 x 10²³ (Approx)
Explanation:
Molar mass of H2S = (1x2) + 32 = 34 g
Total number of molecule = 34 / 35.50
Total number of molecule = 0.9577
Avogadro's number = 6.022 x 10²³
Number of hydrogen sulfide molecule = 0.9577 x 6.022 x 10²³
Number of hydrogen sulfide molecule = 5.7672 x 10²³ (Approx)
