Solution: The burning of fossil fuel by humans in 2012 introduced approximately 8 petagrams (Pg) of carbon per year into the atmosphere in the form of CO2.How many kg of C are placed in the atmosphere each year

Problem

The burning of fossil fuel by humans in 2012 introduced approximately 8 petagrams (Pg) of carbon per year into the atmosphere in the form of CO2.

How many kg of C are placed in the atmosphere each year?

How many kg of CO2 are placed in the atmosphere each year?

A metric ton is 1000 kg. How many metric tons of CO 2 are placed in the atmosphere each year? 

There are 7 billion people on Earh. Find the per capita rate of CO 2 production (tons of CO2 per person per year).

Solution

We are given with the approximate amount of CO[8 petagrams (Pg)] introduced to the atmosphere per year as a result of burning of fossil fuel by humans.


Part A


We are asked to get the mass of Carbon in kg that is placed on the atmosphere per year. We need to get the amount of Carbon in CO2.
