Question

cs₂
express your answer in atomic mass units to two decimal places.
formula mass =
amu

Explanation:

Step1: Identify atomic masses

Carbon (C) has an atomic mass of approximately 12.01 amu, and sulfur (S) has an atomic mass of approximately 32.07 amu. The formula is \( CS_2 \), so there is 1 C atom and 2 S atoms.

Step2: Calculate formula mass

Formula mass = (Atomic mass of C) + 2×(Atomic mass of S) = \( 12.01 + 2\times32.07 \)
First, calculate \( 2\times32.07 = 64.14 \)
Then, add the atomic mass of C: \( 12.01 + 64.14 = 76.15 \)

Answer:

76.15
