What is the number of significant figure is `0.310xx10^(3)`?

Options

A. 2
B. 3
C. 4
D. 6

Explanation

To determine the number of significant figures in the number \(0.310 \times 10^{3}\), we can follow these steps:

### Step 1: Identify the number in scientific notation
The given number is \(0.310 \times 10^{3}\). In scientific notation, the significant figures are determined by the digits in the coefficient (the part before the multiplication by \(10^{n}\)).

### Step 2: Analyze the coefficient
The coefficient here is \(0.310\). To find the significant figures, we need to look at each digit:
- The digit '3' is significant.
- The digit '1' is significant.
- The digit '0' after the decimal point is also significant because it comes after non-zero digits.

### Step 3: Count the significant figures
In \(0.310\), we have:
- 3 significant figures (3, 1, and 0).

### Step 4: Conclusion
Thus, the number of significant figures in \(0.310 \times 10^{3}\) is **3**.

### Final Answer
The number of significant figures in \(0.310 \times 10^{3}\) is **3**.
