Answer: The volume of the container needed is 554.6 L

Explanation:

To calculate the volume of the gas, we use the equation given by ideal gas which follows:

$PV=nRT$

where,

P = pressure of the gas = 3.0 atm

V = Volume of the gas = ? L

T = Temperature of the gas = $25^oC=[25+273]K=298K$

R = Gas constant = $0.0821\text{ L.atm }mol^{-1}K^{-1}$

n = number of moles of propane gas = 68.0 moles

Putting values in above equation, we get:

$3.0atm\times ?L=68mol\times 0.0821\text{ L.atm }mol^{-1}K^{-1}\times 298K\\\\V=\frac{68\times 0.0821\times 298}{3.0}=554.6L$

Hence, the volume of the container needed is 554.6 L

3. How many grams of aluminum can be heated from 90°C to 120°C if 500 J of heat energy are applied?

IgorLugansk [536]

We are given:

Initial Temperature = 90°c

Final Temperature = 120°c

Heat applied(ΔH) = 500 Joules

Specific heat(c) = 0.9 Joules / g°C

Mass of Aluminium(m) = ?

Change in temperature:

ΔT = Final temp. - Inital Temp.

ΔT = 120 - 90

ΔT = 30°c

Calculating the mass:

We know the formula:

ΔH = mcΔT

replacing the values:

500 = m(0.9)(30)

500 = m(27)

m = 500/27

m = 18.52 grams
