Question

18
using your periodic table, calculate the total atomic mass of the compound below: (1 point)
ch4o
29.018 g/mol
16.89 g/mol
28.010 g/mol
32.042 g/mol

Explanation:

Step1: Find atomic masses

From periodic table: \(C = 12.011\space g/mol\), \(H = 1.008\space g/mol\), \(O=16.000\space g/mol\)

Step2: Calculate for \(CH_4O\)

\(1\times12.011+4\times1.008 + 1\times16.000\)
\(=12.011+4.032+16.000\)
\(=32.043\approx32.042\space g/mol\)

Answer:

\(32.042\space \frac{g}{mol}\) (the fourth option)
