    1mole of carbon is equal to its molar mass. Therefore, 1mole/molar mass =.25mole/? Look at the periodic table and look for the molar mass of Carbon. Plug it in to the spot that says molar mass. Then use proportions to figure out your answer. The correct answer should be equal to .25 times molar mass.

    carbon 12 has a mass of 12 g/mole, the values from the periodic table are the average values of all isotopes of carbon weighted by abundance. the mass of .25 moles of carbon 12 is 12 g/mol * 0.25 mol = 3 g

    1 mole of carbon atom has a mass of 24 grams then calculate for .25 moles how much U get... That is 24 Multiplied by .25 .... U will get it!!
