Calculate the Mass of 1.59 Moles of NH3
To find the molar mass of NH3, we add the atomic masses of nitrogen (N) and hydrogen (H).
Molar mass (NH3) = N + 3H
Since the atomic mass of N is 14 and the atomic mass of H is 1, substituting the values gives us: M(NH3) = 14 + 3(1) = 17
Now, we can use the formula moles (n) = mass (m) / Molar mass (M) to find the mass.
Given moles (n) = 1.59 and Molar mass (M) = 17, we can rearrange the formula to solve for mass (m):
m = n * M
Therefore, the mass of 1.59 moles of NH3 is calculated as:
m = 1.59 * 17 = 27.03 grams
So, the mass of 1.59 moles of NH3 is 27.03 grams.
