How many moles of carbon are in a sample of 21.45 moles of heptane(

The number of moles of carbon atom that the given amount of heptane is 150.15 moles

Explanation:

We are given:

Moles of heptane = 21.45 moles

The chemical formula for heptane is

1 mole of heptane contains 7 moles of carbon atom and 16 moles of hydrogen atom

So, 21.45 moles of heptane will contain of carbon atom

Hence, the number of moles of carbon atom that the given amount of heptane is 150.15 moles

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.

is there any options? maybe im just not seeing them but i need the options to
