The molar mass of nitrogen (n2) is 28.02 g/mol. what is the mass, in grams, of 4.60 mol of n2?

The correct answer is 129 grams.  

On the basis of the given data, the molar mass of nitrogen is 28.02 g/mol, the moles of nitrogen given is 4.60 mol. There is a need to calculate the mass of nitrogen.  

In order to calculate the mass, the formula to be used is:  

moles = mass (g) / molar mass (g/mol)

Now by putting the values we get,  

4.60 mol = mass / 28.02 g/mol

mass = 4.60 mol × 28.02 g/mol

mass = 128.892 g or 129 g

Thus, the mass of 4.60 mol of nitrogen is 129 g.  

did you find the answer?

i'm assuming that the correct answer is indeed the first one/ "a"..
