Question

what is the molar mass of ch2o2? 46.03 g/mol 29.0 g/mol 58.0 g/mol

Explanation:

Step1: Find the atomic mass of each element

The atomic mass of \(C = 12.01\space g/mol\), \(H = 1.01\space g/mol\), \(O = 16.00\space g/mol\)

Step2: Calculate the molar mass

For \(CH_2O_2\), there is 1 \(C\) atom, 2 \(H\) atoms and 2 \(O\) atoms.
The molar mass \(M=(1\times12.01)+(2\times1.01)+(2\times16.00)\)
\(M = 12.01+2.02 + 32.00\)
\(M=46.03\space g/mol\)

Answer:

46.03 g/mol
