Answer:

4.6 (Rounded)

Explanation:

Given: 77.5g of NH3

<u>77.5g of NH3</u>

         1

Plug in your units.

<u>77.5g of NH3</u>    x    <u>         mol of NH3  </u>

         1                                g of NH3

Since we are using grams, find the mass of NH3. To save you time, I'll tell you. It's 17.03052.

Now, plug is number into the equation with 1 on the top because you are trying to find 1 moles worth.

<u>77.5g of NH3</u>    x    <u>     1    mol of NH3  </u>

         1                     17.03052g of NH3

Now solve by multiplying the numbers across.

<u>    77.5x1    </u>    = <u>    77.5    </u>   = 4.55065377.

1x17.03052      17.03052
