Answer:
633.5
Explanation:
The total presser is 650.00 mmHg, and it is collected over water, which at 19c is 16.5 mmHg. Therefore, to get the total pressure of H2 you would subtract the partial pressure of water from the total pressure.
650-16.5=633.5
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:

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