Question

what is the molar mass of c2h4o? 1 mol c = 12.01 g c 1 mol h = 1.008 g h 1 mol o = 16.00 g o 1 mol c2h4o = ? g c2h4o round your answer to two decimal places.

Explanation:

Step1: Calculate C mass contribution

$2\times12.01 = 24.02$

Step2: Calculate H mass contribution

$4\times1.008 = 4.032$

Step3: Calculate O mass contribution

$1\times16.00 = 16.00$

Step4: Sum up contributions

$24.02+4.032 + 16.00=44.052$

Answer:

$44.05$
