The mass of a ball is 1.76kg. The mass of 25 such balls is

Options

A. `0.44 xx 10^(3) kg`
B. 44.0 kg
C. 44kg
D. 44.00kg

Explanation

To find the mass of 25 balls given that the mass of one ball is 1.76 kg, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the mass of one ball**:
The mass of one ball is given as 1.76 kg.

2. **Determine the number of balls**:
We need to find the mass of 25 such balls.

3. **Calculate the total mass**:
The total mass of 25 balls can be calculated using the formula:
\[ \text{Total Mass} = \text{Mass of one ball} \times \text{Number of balls} \]
Substituting the values:
\[ \text{Total Mass} = 1.76 \, \text{kg} \times 25 \]

4. **Perform the multiplication**:
\[ 1.76 \times 25 = 44.0 \, \text{kg} \]

5. **Consider significant figures**:
The mass of one ball (1.76 kg) has three significant figures. Therefore, the total mass must also be expressed with three significant figures. The result, 44.0 kg, has three significant figures (the zero after the decimal point counts as significant).

6. **Final Answer**:
The mass of 25 balls is 44.0 kg.

### Summary:
The mass of 25 balls is **44.0 kg**.
