The time the chocolate bar could power the laptop in hours is 0.00233 hrs.
Since 200 Calories of chocolate bar were burned to power the 100 Watt laptop, we need to find the number of joules on energy in 200 calories of chocolate bar.
Knowing that 4.2 Joules = 1 Calorie, then
200 Calories = 200 × 1 calorie = 200 × 4.2 Joules = 840 Joules
Since the power required by the laptop is 100 W = 100 J/s and Power, P = energy/time
so, time = energy/power
So, the time for the laptop to use 840 J of energy from the chocolate bar at a rate or power of 100 W = 100 J/s is
time = 840 J ÷ 100 J/s = 8.4 s
So, the time in hours is 8.4 s ÷ 3600 s/1 h = 0.00233 hrs (since 1 hr = 3600 s)
So, the time the chocolate bar could power the laptop in hours is 0.00233 hrs.

We calculate first the initial pressure of the gas.
P = nRT/V
= (0.215 g/mL)(1 mol/16 g)(0.0821 L.atm/mol K)(302K)
= 0.333 atm
Using the relationship between the pressure and temperature,
P1/T1 = P2/T2
Substituting the known values,
(0.333 atm) / (29 + 273) = P2/(950)
P2 = 1.05 atm
