If one mole of carbon atoms weigh 12 gram,what is the mass in gram of 1 atom of carbon?
1moleofCatoms=6.022×1023atomsofC=12g(Given)Thus,6.022×1023atomsofcarbonhavemass=12gTherefore,1atomofcarbonwillhavemass=126.022×1023g=1.993×10-23g.Hence,massof1atomofcarbonis1.993×10-23g.
Question 1If one mole of carbon atoms weighs 12 grams, what is the mass (in grams) of 1 atom of carbon?
