fiasKO [112]4 years ago
5 0
N₂ + 3 H₂ → 2 NH₃

number of moles of N₂ = 38 g / 28 g/mol = 1.357 mol

1 mole of N₂ gives 2 moles of NH₃
1.357 mol of N₂ will give ?? mole NH₃

= 2 x 1.357 = 2.7 mol NH₃

Imagine we have <span>mass of solvent 1kg (1000g)
According to that: </span>molality =n(solute) / m(solvent) =\ \textgreater \  4.8m = 4.8mole / 1kg

Determine the grams of protein in one cup of soup that has 140 kcal with 8 g of carbohydrate and 2 g of fat.
irina [24]

There are 22.5 grams of protein in one cup of soup that has 140 kcal with 8 g of carbohydrate and 2 g of fat.

<h3>What is the mass of a substance?</h3>

The mass of a substance is the quantity of the substance that is being measured in grams or kilograms.

To determine the energy from the 8g of carbohydrate, we have:

= 8g × 4 kcal/g (the corresponding calories of food type)

= 32 kcal

The energy from 2g of fat = 2g × 9 kcal/g

= 18 kcal

The energy from protein is calculated as:

= 140 kcal - 32 kcal - 18 kcal

= 90 kcal

The required mass of the protein in grams is:

\mathbf{= 90 \ kcal \times \dfrac{1}{4 \  kcal }}

= 22.5 grams

Therefore, we can conclude that there are 22.5 grams of protein in one cup of soup.
