One egg has a mass of about 65 g, what is the mass of 2 dozen eggs ?

Question

Accepted Answer

To determine the mass of 2 dozen eggs, we need to first understand the given information and perform the necessary calculations.

1. **Understanding the Problem:**
   - One egg has a mass of about 65 grams.
   - A dozen eggs means 12 eggs.
   - Therefore, 2 dozen eggs would be 24 eggs (since 2 x 12 = 24).

2. **Calculating the Total Mass:**
   - The mass of one egg is 65 grams.
   - The mass of 24 eggs (2 dozen) would be calculated as follows:
     $$
     \text{Mass of 24 eggs} = 24 \times 65 \text{ grams}
     $$
   - Performing the multiplication:
     $$
     24 \times 65 = 1560 \text{ grams}
     $$

3. **Converting Grams to Kilograms:**
   - We know that 1000 grams is equal to 1 kilogram.
   - Therefore, 1560 grams can be converted to kilograms:
     $$
     1560 \text{ grams} = 1 \text{ kilogram} + 560 \text{ grams} = 1.56 \text{ kilograms}
     $$

4. **Justifying Option 1:**
   - Option 1 states that the mass of 2 dozen eggs is 1.56 kg.
   - Our calculation confirms that 1560 grams is indeed 1.56 kg, which matches Option 1 perfectly.

5. **Explaining Why Other Options Are Incorrect:**
   - **Option 2 (1 kg 56 g):** This option suggests the mass is 1056 grams, which is incorrect because our calculation shows the mass is 1560 grams.
   - **Option 3 (1.304 kg):** This option suggests the mass is 1304 grams, which is incorrect as it does not match our calculated mass of 1560 grams.
   - **Option 4 (1 kg 544 g):** This option suggests the mass is 1544 grams, which is incorrect because our calculation shows the mass is 1560 grams.

In conclusion, based on the calculations and logical reasoning, Option 1 is the correct answer as it accurately represents the mass of 2 dozen eggs as 1.56 kg.
