Question

A sample of hydrogen sulfide, H2S, has a mass of 35.50 g. Calculate the number of hydrogen sulfide molecules in the sample.

Answer 1

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)
