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.  

they both have a y in them

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
