Answer

To determine the two insignificant digits in the value 2.7465 g, which contains only three significant figures, we can follow these steps:

### Step 1: Identify the significant figures
Significant figures are the digits in a number that contribute to its accuracy. This includes all non-zero digits, any zeros between significant digits, and any trailing zeros in the decimal portion.

In the number 2.7465:
- The first significant figure is '2'

- The third significant figure is '4'

### Step 2: Determine the total number of digits
The number 2.7465 has a total of five digits: 2, 7, 4, 6, and 5.

### Step 3: Identify the insignificant digits
Since we are told that only three significant figures are to be considered, we need to identify which digits are not significant. The insignificant digits are the ones that come after the third significant figure.

In this case:
- The fourth digit is '6'
- The fifth digit is '5'

### Conclusion
Thus, the two insignificant digits in the value 2.7465 g are **6 and 5**.

### Final Answer
The two insignificant digits are **6 and 5**.
