0.058 moles of NH3 weighs how much grams?
How much does 1 mol NH3 weigh? Would it be about 17 g? Then how much mass is in 0.058 mole?
.9883 g
.058 _17.04_____= .9883
1 mole
Calculate the following: 0.058 moles of NH3 Weighs?
To find the mass of NH3 (Ammonia) in grams, you will need to use its molar mass. The molar mass of NH3 is calculated by adding up the atomic masses of all the atoms in one molecule of NH3.
The atomic mass of nitrogen (N) is approximately 14.01 g/mol, and the atomic mass of hydrogen (H) is approximately 1.01 g/mol.
To calculate the molar mass of NH3, you need to multiply the atomic mass of nitrogen by its subscript (1), and the atomic mass of hydrogen by its subscript (3), and then add the two results together:
Molar mass of NH3 = (atomic mass of N x subscript of N) + (atomic mass of H x subscript of H)
= (14.01 g/mol x 1) + (1.01 g/mol x 3)
= 14.01 g/mol + 3.03 g/mol
= 17.04 g/mol
Now that we have the molar mass of NH3, we can calculate the mass of 0.058 moles of NH3. We can use the molar mass as a conversion factor to convert from moles to grams.
Mass = number of moles x molar mass
= 0.058 moles x 17.04 g/mol
≈ 0.990 g
Therefore, 0.058 moles of NH3 weighs approximately 0.990 grams.
