The french fries gives 460 kilocalories and <span>65% of those calories come from fat. Then, calorie that comes from fat would be: 65% * 460 kcal= 299 kcal
Fat gives </span>energy about 9kcal/gram. Then, the total mass of fat in the french fries would be: 299 kcal/ (9kcal/g)= 33.22 grams

Answer:
Mass = 159.8 g
Explanation:
Given data:
Mass of HNO₂ = ?
Moles of nitrous acid = 3.4 mol
Solution:
Formula:
Number of moles = mass / molar mass
We will rearrange this formula.
Mass = number of moles × molar mass
Molar mass of nitrous acid = 47 g/ mol
Mass = 3.4 mol × 47 g/ mol
Mass = 159.8 g
