When 28 g of nitrogen and 6 g of hydrogen react, 34 g of ammonia are produced. If 100 g of nitrogen react with 6 g of hydrogen,
love history [14]

Answer:

34 g

Explanation:

Let's consider the following balanced equation.

N₂ + 3 H₂ → 2 NH₃

The theoretical mass ratio of N₂ to H₂ is 28g N₂ : 6g H₂ = 4.6g N₂ : 1g H₂.

The experimental mass ratio of N₂ to H₂ is 100g N₂ : 6g H₂ = 16.6g N₂ : 1g H₂.

As we can see, hydrogen is the limiting reactant.

According to the task, we 6 g of H₂ react completely, 34 g of ammonia are produced.

A certain liquid has a density of 2.67 g/cm3. 30.5 ml of this liquid would have a mass of __________ kg.
8090 [49]
Hey there!

Density = 2.67 g/cm³

volume = 30.5 mL

Mass = density *volume

Mass = 2.67 * 30.5

Mass = 81.435 g

Therefore:

Mass in kg :

1 kg -------------- 1000 g
?? ----------------- 81.435 g

mass = 81.435 * 1 / 1000

mass = 0.081435 kg
