WebJul 16, 2016 · In this example you have 0.2 grams of carbon atoms. The first step is to find out how many moles this is. The molar mass of carbon is 12.01 g/mol, you have 0.2 gram so: #0.2 color(red)cancel(color(black)(g)) / (12.01 color(red)cancel(color(black)g)/(mol)) = 0.01665... mol# The number of atoms can be calculated using Avogadro's constant that ... WebWe know that the molar mass of 1 mole of carbon is equal to 12. It means that 12 grams per mole Also, the Avogadro constant is 6.02 x 1023 So, the conversion of carbon from grams …
