Answer is: V has the units of liters, and T has the units of kelvin.
Ideal gas law: p·V = n·R·T.
atm · L = mol · L·atm/mol·K · K; both side of equatation have same values.
R = 0,08206 L·atm/mol·K; universal gas constant.
p is pressure of the gas, unit is standard atmosphere (atm).
V is volume of the gas, unit is liters (L).
n is amount of substance of the gas; unit is mole (mol).
T is temperature of the gas, unit is Kelvin (K).

Answer: 10.3 grams of Copper oxide is left unreacted.
Explanation:
To calculate the moles :
The balanced chemical reaction is:
According to stoichiometry :
1 moles of require = 1 mole of
Thus 0.5 moles of will require= of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
moles of CuO left = (0.63-0.5) mol= 0.13 mol
Mass of left =
10.3 grams of Copper oxide is left unreacted.
Your answer would be shorter wavelength and equal speed !
