Calculate the amount of upper (m moles) m a 36 g pure copper sheet (mm of copper - 36.55 g/mol)

Explanation / Answer

Anwer of Question (8)

Use the ideal gas law: PV = nRT
The units of P are atm
The units for V are liters
n = moles
R = .0821
T = Temp. in Calvin

25 C = 298 Calvin

P (10.2) = 0.44(.0821) (298)

P = 1.055 atm
