Answer:

2.71 L

Explanation:

Charle's Law:

V1 / T1 = V2 / T2 or V1 / V2 = T1 / T2

Conversion to SI unit: Cesius (C) to Kelvin ( K)

K = C + 273

V2 = ( V1 × T2) / T1

V1 = 2.5 L

V2 = ?

T1 = 25° C

T2 = 60° C

2.5 / (25 + 273) = V2 / ( 50 + 273)

V2 = 2.5(50 + 273) / ( 25 + 273)

= 2.5(323) / 298

= 807.5 / 298

= 2.71 L
