Question

Calculate the mass of ammonia gas produced if 2.8 gram of nitrogen gas reacts with hydrogen gas determine the moles of hydrogen gas reacted also calculate volume of ammonia gas produced at stp

Answer 1

Answer:

mass of ammonia is 3.4 g

volume of ammonia is 4.48l

explanation:

N2 + 3 H2----------2 NH3

here given mass of ammonia is 2.8g so we can find its mole = 2.8/28 = 0.1

according to mole concept

1 mole of N2 is equal to 2 mole of ammonia.

therefore we found that mole of ammonia is 0.2 mole

so mass of amonia = 0.2 × 17 = 34

and volume = mole × 22.4

= 0.2×22.4= 4.48l
