Adding 50 grams of gelatin and 400 grams of water will give us a mixture with a total mass of 450 grams. The percent mass of water is calculated by dividing the mass of water by the total mass and multiply by 100.
                      mass % = (400 / 450) x 100% = 88.89%
Thus, there is approximately 88.90% of water in the sample.

Calculate the molar mass of NH4NO3. Molar mass of NH4NO3 = g/mol.
bija089 [108]

The molar mass of NH4NO3 in g/mol is 80g/mol.

HOW TO CALCULATE MOLAR MASS:

The molar mass of a compound can be calculated by summing the atomic masses of its constituent elements.

In ammonium nitrate (NH4NO3), there are nitrogen, hydrogen, and oxygen elements.

  • Atomic mass of nitrogen = 14
  • Atomic mass of oxygen = 16
  • Atomic mass of hydrogen = 1

Molar mass of NH4NO3 = 14 + 1(4) + 14 + 16(3)

Molar mass of NH4NO3 = 80g/mol

  • Therefore, the molar mass of NH4NO3 in g/mol is 80g/mol.

How can you obtain hydrogen from a mixture of ethene, hydrogen and ammonia gases?​
irga5000 [103]

Answer:

We normally separate unreacted hydrogen from ammonia (product) in Haber process. The reaction mixture contains some ammonia, plus a lot of unreacted hydrogen and nitrogen. The mixture is cooled and compressed, causing the ammonia gas to condense into a liquid.
