Answer:
203.63 K
Explanation:
Using Charles law equation,
V1/T1 = V2/T2
Where;
V1 = initial volume (mL)
V2 = final volume (mL)
T1 = initial temperature (K)
T2 = final temperature (K)
According to the information in this question,
V1 = 675.6 mL
V2 = 410.9 mL
T1 = 61.8°C = 61.8 + 273 = 334.8K
T2 = ?
Using V1/T1 = V2/T2
675.6/334.8 = 410.9/T2
Cross multiply
675.6 × T2 = 334.8 × 410.9
675.6T2 = 137569.32
T2 = 137569.32 ÷ 675.6
T2 = 203.63 K
