50.0ml

Explanation:

$P_{1} = 785.0 Torr$ $P_1 = 785.0"Torr"$ => $P_{2} = 745.0 Torr$ $P_2=745.0"Torr"$
Decreasing Pressure => Increasing Volume (Boyles Law) => Use ratio of pressure values that decrease $V_{1}$ $V_1$ . => (785.0/745.0)

$T_{1} = (15 + 273) K = 288 K$ $T_1=(15 + 273)K = 288K$ => $T_{2} = (30 + 273) K = 303 K$ $T_2=(30 + 273)K= 303K$
Increasing Temperature (Charles Law) => Increasing Volume => Use ratio of temperature values that increase $V_{1}$ $V_1$ . => (303/288)

$V_{1} = 45.0 m l$ $V_1=45.0ml$ => $V_{2} = ?$ $V_2=?$

$V_{2} = 45.0 m l \times \frac{785.0 Torr}{745.0 Torr} \times \frac{303 K}{288 K}$ $V_2 = 45.0mlxx(785.0"Torr")/(745.0"Torr")xx(303K)/(288K)$ = $49.9 m l \Rightarrow 50.0 m l$ $49.9ml => 50.0ml$
