Afina-wow [57]

Answer:

22 percent of Calories in a serving comes from added sugars

Explanation:

Sugars mentioned in the food products are usually processed sugars, chemically called fructose (which is a combination of glucose and sucrose). Sugars gives four Calories of energy per gram. So, 13 grams of sugar will give thirteen times of four, which is 52 Calories.

The percentage can be calculated from the following formula:

Percentage= (\frac{Calories from sugars}{TotalCalories perserving})(100)

Percentage= (\frac{52}{240})(100)\\ \\ Percentage= 22

Answer:

0.373 moles of ammonium carbonate

Explanation:

To solve this question we must find the molar mass of ammonium carbonate. With the molar mass and the mass we can find its moles, as follows:

(NH₄)₂CO₃ contains: 2 moles N, 8 moles H, 1 mole C, 3 moles O. Molar mass:

2N = 14.0g/mol*2 = 28.0

8H = 1.0g/mol*8 = 8.0

1C = 12.0g/mol*1 = 12.0

3O = 16.0g/mol*3 = 48.0

Molar mass: 28.0 + 8.0 + 12.0 + 48.0 = 96.0g/mol

The moles of ammonium carbonate in 35.8g are:

35.8g * (1mol / 96.0g) =
