The mineral orpiment, having the empirical formula As2S3, was used in ancient times as a cosmetic. What mass of arsenic is prese
Soloha48 [4]

Answer : The mass of arsenic present in 5.0 g of orpiment is, 1.5 grams.

Explanation : Given,

Mass of orpiment = 5.0 g

As we know that the molar mass of As_2S_3 is, 246.02 g/mol and the molar mass of As is, 75 g/mol.

As per the question, we conclude that:

As, 246.02 g of As_2S_3 contains mass of arsenic = 75 g

So, 5.0 g of As_2S_3 contains mass of arsenic = \frac{5.0}{246.02}\times 75=1.5g

Thus, the mass of arsenic present in 5.0 g of orpiment is, 1.5 grams.
