Answer 2

To determine the mass of each component and calculate their ratio, let's break down the ingredients used by your mother to make cocoa for breakfast:

1. Cocoa powder: 1 teaspoon 2. Sugar: 2 teaspoons 3. Milk: 1 glass

To calculate the mass of each component, we need to know the density of the ingredients. The density of cocoa powder is approximately 0.59 g/mL, the density of sugar is approximately 0.85 g/mL, and the density of milk is approximately 1.03 g/mL.

Using these densities, we can calculate the mass of each component:

1. Cocoa powder: 1 teaspoon is approximately 5 grams. Therefore, the mass of cocoa powder is 5 grams. 2. Sugar: 2 teaspoons is approximately 10 grams. Therefore, the mass of sugar is 10 grams. 3. Milk: 1 glass is not specific enough to determine the exact volume. However, a typical glass of milk is around 250 mL. Therefore, the mass of milk is approximately 257.5 grams (250 mL * 1.03 g/mL).

Now, let's calculate the ratio of each component:

1. Cocoa powder: The ratio of cocoa powder to the total mass of the ingredients is 5 grams / (5 grams + 10 grams + 257.5 grams) ≈ 0.018 or 1.8%. 2. Sugar: The ratio of sugar to the total mass of the ingredients is 10 grams / (5 grams + 10 grams + 257.5 grams) ≈ 0.036 or 3.6%. 3. Milk: The ratio of milk to the total mass of the ingredients is 257.5 grams / (5 grams + 10 grams + 257.5 grams) ≈ 0.945 or 94.5%.

Therefore, the ratio of cocoa powder, sugar, and milk in the cocoa prepared by your mother is approximately 1.8%, 3.6%, and 94.5%, respectively.

Please note that these calculations are approximate and based on the given information. The actual values may vary depending on the specific brands and types of ingredients used.
