The Mond process produces pure nickel metal via the thermal decomposition of nickel tetracarbonyl: Ni(CO) ₄ (l) → Ni (s) + 4CO (g) .
What volume (L) of CO is formed from the complete decomposition of 444 g of Ni(CO) ₄at 752 torr and 22.0 °C?

First, calculate moles of Ni(CO)₄: Molar mass = 170.73 g/mol, so 444 g is 2.6 mol. The reaction produces 4 moles of CO per mole of Ni(CO)₄, so 2.6 mol Ni(CO)₄ produces 10.4 mol CO. Use the ideal gas law: PV = nRT. Convert 752 torr to atm (752/760 = 0.989 atm) and 22°C to Kelvin (295 K). R = 0.0821 L·atm/mol·K. V = nRT/P = (10.4 mol)(0.0821 L·atm/mol·K)(295 K)/(0.989 atm) = 255 L.
