help me with this. thank you.

L-atm- 4. Starting from the universal gas constant (R = 0.0821 a), determine the volume (in L) occupied by %3D mol-K 2.45 moles of an ideal gas at 32.0°C and a pressure of 0.956 atm. 5. Cadmium (Cd) is a heavy.metal which has a leaching rate of about 0.0012 mg/L per year. Consider a lake which has a volume of 2.25 x 10° L, and initially contains 0.002 kg of Pb. Determine the amount of Pb (in kg) present in the lake after 5.0 years assuming that there is no evaporation of water from the lake's surface.
