Question

any mods please help​

Answer 1

1. 60 gram of ch3cooh

Molar mass :- 12+3+12+16+16+1

> 60

Number of moles = given mass/molar mass = 60/60 = 1 mole

2. 51 grams of ch4

Molar mass :- 12+4 = 16

Number of moles = 51/16 = 3.1875 moles approx

3. 11 grams of CO2

Molar mass:- 12+16+16 = 44

Number of moles= 11/44 = 0.25 moles approx

4. 90 grams of H2O

Molar mass:- 16+2 = 18

Number of moles = 90/18 = 5 moles approx
