Question

calculate the molecular mass of the following a.water h2o b. carbin di oxide co2 c. metane ch2​

Answer 1

Answer:

H20 - mass of 2H2 + O2

- 2×1 +16=18 gm / molar

CO2- mass of C+O2

- 12+ 2 ×16 =44gm / molar

CH4- mass of C +4 H2

- 12+4×1=16gm / molar

Explanation:

CH4 is methane and CH2 is methylene CH2- mass of C and 2H2

- 12+ 2×1=16gm/ molar
