Answer:
0.057 M
Explanation:
To find the new molarity, you need to (1) find the moles (via the molarity equation using the old molarity and volume) and then (2) calculate the new molarity (via the molarity equation using the combined volume and old moles).
<u>(Step 1)</u>
60 mL / 1,000 = 0.06 L
Molarity (M) = moles / volume (L)
1.0 M = moles / 0.06 L
(1.0 M) x (0.06 L) = moles
0.06 = moles
<u>(Step 2)</u>
0.06 L + 1 L = 1.06 L
Molarity (M) = moles / volume (L)
Molarity = 0.06 moles / 1.06 L
Molarity = 0.057 M

Answer:
Energy in foods is provided by macro-nutrients.
Explanation:
Nutrients are “environmental substances” used for growth, energy, and bodily functions of the organisms. Those nutrients that are required in larger amounts are called macro-nutrients.
There are 3 macro-nutrients needed by humans: lipids (fats), carbohydrates (sugar) and proteins. All these macro-nutrients gives energy in form of “calories”. For example:
- In carbohydrates, there are '4 calories' of energy per gram.
- In proteins, there are '4 calories' of energy per gram.
- And in lipids, there are '9 calories' of energy in one gram.
This means that if you look at a food label and it lists 10 grams of carbohydrates, 0 grams of protein, and 0 grams of fat, that food would contain 40 calories.
