Carbon has two stable isotopes; 12c (98.93%) and 13c (1.07%). how many atoms of 13c would there be in a 2.05 g sample of carbon dioxide?

There are atoms of 13-C present in a 2.05 grams sample of carbon dioxide.

Explanation:

Percentage of 12-C isotope = 98.93%

Percentage of 13-C isotope = 1.07%

Mass of the sample of carbon dioxide = 2.05 g

Mass of 13-C in the sample = 1.07% of 2.05 g

Molar mass of 13-C isotope = 13 g/mol

Moles of 13-C =

atoms/ molecules

Atoms of 13-C in 0.001687 moles:

There are atoms of 13-C present in a 2.05 grams sample of carbon dioxide.

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
