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 when the mass of one ball is given as 1.76 kg, we can follow these steps:

### Step 1: Identify the mass of one ball
The mass of one ball is given as:
\[ \text{Mass of one ball} = 1.76 \, \text{kg} \]

### Step 2: Calculate the mass of 25 balls
To find the total mass of 25 balls, we multiply the mass of one ball by the number of balls:
\[ \text{Mass of 25 balls} = 25 \times 1.76 \, \text{kg} \]

### Step 3: Perform the multiplication
Calculating the above expression:
\[ \text{Mass of 25 balls} = 25 \times 1.76 = 44.00 \, \text{kg} \]

### Step 4: Determine significant figures
Now, we need to express the result in the correct number of significant figures. The mass of one ball (1.76 kg) has 3 significant figures. Since the number 25 is a counted quantity, it has an infinite number of significant figures.

### Step 5: Final answer with correct significant figures
The result of our calculation is 44.00 kg. However, we must express this value using the smallest number of significant figures from our measurements. Since 1.76 kg has 3 significant figures, we will round our answer to 3 significant figures:
\[ \text{Final answer} = 44.0 \, \text{kg} \]

### Summary
The mass of 25 balls is:
\[ \text{Mass of 25 balls} = 44.0 \, \text{kg} \]
