If 9.5 × 10²⁵ molecules of CO₂ are produced in a combustion reaction, what is the mass in kg of CO₂ that is produced?

6.9428 kg of CO2

Explanation:

1) Use Avogadro's number that states 1 mole = 6.022 x 10^23 particles. Convert 9.5 x 10^25 molecules into moles.

9.5 x 10^25 CO2 molecules = 157.75 moles CO2

2) Convert 157.75 moles of CO2 into grams. CO2's molar mass is 44.01g.

= 6942.79g

3) Convert 6942.79 grams into kilograms (divide by 1000):

6.9428 kg

r just means there's a number of carbon in teh chain. for example rcooh means that after x number of carbon, the chain ends with cooh.
