2C₂H6 + 702 - >4C02 + 6H₂O

If you used 4.88x10^25 molecules of C2H6 to start a

fire, how many molecules of CO2 did you Create?

975.56*10²³ molecules

Explanation:

Given dа ta:

Number of molecules of C₂H₆ = 4.88*10²⁵

Number of molecules of CO₂ produced = ?

Solution:

Chemical equation:

2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O

Number of moles of C₂H₆:

1 mole = 6.022*10²³ molecules

4.88*10²⁵ molecules*1mol/6.022*10²³ molecules

0.81*10² mol

81 mol

Now we will compare the moles of C₂H₆ with CO₂.

C₂H₆ : CO₂

2 : 4

81 : 4/2*81 = 162 mol

Number of molecules of CO₂:

1 mole = 6.022*10²³ molecules

162 mol * 6.022*10²³ molecules / 1 mol

975.56*10²³ molecules
