Convert the following moles into masses

2.00 moles of N2

n=14g

2 x 14 =28
2.00mols x 28 = 56 mols

good job ... but watch the units

56 is grams

2.00 moles * 28 grams/mole = 56 grams

ok thanks !

To convert moles into masses, you would need to use the molar mass of the substance. In this case, the substance is N2, which is nitrogen gas. The molar mass of nitrogen (N) is 14 grams per mole.

To find the molar mass of N2, you simply multiply the molar mass of nitrogen (14 g/mol) by the number of nitrogen atoms in the molecule, which is 2:

Molar mass of N2 = 2 x 14 g/mol = 28 g/mol

Now, to convert 2.00 moles of N2 into grams, you can use the formula:

Mass (g) = Number of moles x Molar mass

Mass (g) = 2.00 moles x 28 g/mol = 56 grams

Therefore, 2.00 moles of N2 is equivalent to 56 grams.
