atoms of Zn in 0.750 mols of Zn.
To find the number of carbon atoms, we <span>multiply </span>the 3.28x10^24 by the ratio, 3/8. The total number of carbon atoms is 1.23 x 10^24 atoms. The total mass of the sample is each number of atoms divided by avogadro's number and multiplied by the molar mass of each. The total mass is 29.96 grams.
Answer:
The element is Dysprosium.
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.
