What is the number of moles and the number of atoms in 2.30 grams of sodium?
From the periodic table, 1 mole of sodium is 22.989770g. To find the number of moles in 2.30g, multiply the known mass x (1mol/22.989770g). 2.30g Na X (1mol Na/22.989770g Na) = 0.100mol Na* * The answer is in 3 significant figures because 2.30g has 3 significant figures. When you multiply or divide, the answer is rounded to the same number of significant figures as are found in the number with the fewest significant figures.
