In a part we have 1 petagram.
00:05
1 petagram that is pg is equal to 10 to 15 gram.
00:14
1 kilogram is equal to 1000 gram.
00:19
So 7 .9 pg or petagram of carbon.
00:26
Carbon is 7 .9 into 10 to power raise 13 gram of carbon.
00:35
That is the answer of the a part here.
00:39
Then we talk about the b part.
00:42
And that is mass of carbon dioxide is equal to 7 .9 into 10 to power raise 13 gram of carbon.
00:59
Multiply by 14 gram of carbon dioxide divided by 12 gram of carbon.
01:14
So here we have this.
01:16
How we get this 14 gram? and that 14 gram we have the mass of the carbon that is 12 .01 plus 2 into 16 .00 gram per mole.
01:33
So it give rise to 44 gram that we have gram written here.
01:37
So now when we solving this we get the 2 .8993 into 10 to power raise 13 gram of carbon dioxide.
01:54
That is the answer of the b part here...
