How many g of co2 are produced by5 moles of c3 h8

660g of CO2

Explanation:

First, we need to generate a balanced equation for the reaction. This is given below:

C3H8 + 5O2 —> 3CO2 + 4H2O

From the equation,

1mole of C3H8 produced 3moles of CO2.

Therefore, 5moles of C3H8 will produce = 5 x 3 = 15moles of CO2.

Now let us convert 15moles of CO2 to grams. This is illustrated below:

Molar Mass of CO2 = 12 + (2x16) = 12 + 32 = 44g/mol

Number of mole of CO2 = 15moles

Mass of CO2 =?

Number of mole = Mass /Molar Mass

Mass = number of mole x molar Mass

Mass of CO2 = 15 x 44 = 660g

Therefore, 5moles of C3H8 will produce 660g of CO2

the answer is c.the valence of the atoms combine .
