1. Use the equation below for the following question.
zhuklara [117]

Answer:

120.44 × 10²³ molecules

Explanation:

Given data:

Moles of C₃H₈ = 5.0 mol

Molecules of water produced = ?

Solution:

Chemical equation:

C₃H₈ + 5O₂ → 3CO₂ + 4H₂O

Now we will compare the moles of C₃H₈ and water.

                     C₃H₈           :         H₂O

                         1              ;             4

                        5              :            4×5 = 20 mol

Molecules of water:

1 mole = 6.022 × 10²³ molecules

20 mol×6.022 × 10²³ molecules / 1 mol

120.44 × 10²³ molecules

a fruit and oatmeal bar contains 142000 calories.

A nutritional calorie, or kilocalorie, is equal to 1000 calories.

E = 142 kcal · 1000 cal/kcal.

E = 142 000 cal.

Calorie (cal), or small calorie, is the amount of energy needed to heat one gram of water by one degree Celsius.

One small calorie is approximately 4.2 joules.

A calorie is a unit of energy.
