Explanation:

Step1: Apply Boyle's Law formula

$P_1V_1 = P_2V_2$

Step2: Rearrange for unknown volume

$V_2 = \frac{P_1V_1}{P_2}$

Step3: Substitute given values

$V_2 = \frac{2.1\ \text{atm} \times 0.45\ \text{L}}{1.5\ \text{atm}}$

Step4: Calculate and round to 2 sig figs

$V_2 = 0.63\ \text{L}$

Answer:

0.63
