Question

A dandruff shampoo contains dipyrithione, C10H8N2O2S2, which acts as an antibacterial and antifungal agent. What is the molar mass of dipyrithione?

Express your answer using two decimal places and include the appropriate units.

​

Answer 1

Molar mass of dipyrithione is 252.12 g/mol

Step-by-step explanation:

Dipyrithione → C₁₀H₈N₂O₂S₂

In order to determine the molar mass we should multiply the molar mass of each element, to the amount of atoms, in the main formula:

Molar mass Dipyrithione = Molar mass C . 10 + Molar Mass H . 8 + Molar mass N . 2 + Molar mass O . 2 + Molar mass S . 2

12 g/mol . 10 + 1 g/mol . 8 + 14 g/mol . 2 + 16 g/mol . 2 + 32.06 g/mol . 2 =

252.12 g/mol
