Question

Calculating the volume of CO2 when 0.3 mol of oxygen is used in a reaction

Answer 1

Answer:

6.67ml

Explanation:

C +O2= CO2

1:1:1 is ratio of reaction

it can be written as 0.3:0.3:0.3

1mol O2 = 32g

0.3mol= 9.6g

0.3 mol C = 3.6g

total weight = 13.2g

CO2= 13.2g = 0.0132kg

1.98kg/m^3 is density of CO2

mass/density= volume

0.0132/1.98 = 6.67 *10^-3 L

= 6.67ml.
