Let us look at the following equations

3N

As per the above equation 3 moles of N

in terms of molar mass , one mole of N

3 mole of N

46 x 3 g of N

138 g of N

To get 1 g of HN

To get 1 g of HN

To get 63.0 g of HN

69.3 g of N

The answer is

Starting from the balanced chemical equation

one can see that we have a

Now, starting from the given mass of nitric acid,

**moles** (knowing that nitric acid's molar mass is

Therefore, the number of

**moles**

Using the same conversion between moles and mass, one can determine that
