Answer:
140.25g of CO2
Explanation:
First, let us write a balanced equation showing how CO2 is produced from CH4. This is illustrated below:
When CH4 undergoes combustion it produces CO2 and H2O according to the balanced equation below:
CH4 + 2O2 —> CO2 + 2H2O
Next, let us calculate the mass of the CH4 that reacted and the mass of CO2 produced from the balanced equation. This is shown below:
Molar Mass of CH4 = 12 + (4x1) = 12 + 4 = 16g/mol
Molar Mass of CO2 = 12 + (2x16) = 12 + 32 = 44g/mol
From the balanced equation above,
16g of CH4 produced 44g of CO2.
Therefore, 51g of CH4 will produce = (51 x 44)/16 = 140.25g of CO2.
From the calculations made above, we can see that 51g of CH4 produced 140.25g of CO2
Answer:
139.91 g CO2 to the nearest hundredth.
Explanation:
CH4 + 2O2 ----> CO2 + 2H2O
Using the molar masses of the chemicals:
(12.011 + 4*1.008) g CH4 produces (12,011 + 32) g CO2
So 51 g of CH4 produces [51 * (12,011 + 32] / [ (12.011 + 4*1.008) ]
= 139.91 g CO2.
