Question
??
### Significant Figures in Scientific Calculations This question focuses on expressing a calculated value with the correct number of significant figures (sig figs). **Problem Statement:** Given, at constant n (amount of substance) and T (temperature): - \( P_1 = 1.3 \, \text{atm} \) - \( V_1 = 25.0 \, \text{L} \) - \( P_2 = 20 \, \text{atm} \) The value of \( V_2 \) is calculated to be 1.625 L. How would you express \( V_2 \) to the correct number of sig figs? **Options:** - 1.62 L - 1.625 L - **1.6 L** (This option is selected) - 2 L - 2.0 L **Explanation:** The number of significant figures is crucial when reporting scientific measurements and calculations. In this scenario, the pressures \( P_1 \) and \( P_2 \) have two significant figures (1.3 and 20), and the initial volume \( V_1 \) has three significant figures (25.0). When calculating or expressing the result \( V_2 \), it must be reported with the same number of significant figures as the measurement with the fewest significant figures, which is 2. Hence, the correct expression of \( V_2 \) is 1.6 L.
