Question

what is the molar mass of ch2cl2?
1 mol c = 12.01 g c
1 mol h = 1.008 g h
1 mol cl = 35.45 g cl
1 mol ch2cl2 = ? g ch2cl2
round your answer to two decimal places.

Explanation:

Step1: Calculate the mass of C

There is 1 C atom in \(CH_2Cl_2\). Mass of C: \(1\times12.01 = 12.01\) g

Step2: Calculate the mass of H

There are 2 H atoms. Mass of H: \(2\times1.008=2.016\) g

Step3: Calculate the mass of Cl

There are 2 Cl atoms. Mass of Cl: \(2\times35.45 = 70.9\) g

Step4: Sum up the masses

Molar mass of \(CH_2Cl_2\): \(12.01+2.016 + 70.9=84.926\approx84.93\) g

Answer:

\(84.93\)
