How many liters of carbon monoxide gas are formed if 0.75 moles of carbon react completely with silicon dioxide (Assume this reaction occurs at STP.)?
Start with a balanced equation.
2C + SiO₂ --> 2CO + Si
The mole ratio between C and CO is 1:1 in the balanced equation. Therefore, 0.75 mol C will produce 0.75 mol CO if reacted completely with SiO₂.
There are two methods for determining the volume of CO produced at STP.
Method 1: Molar Volume
At STP defined as 0 °C (32 °F, 273.15 K) and 1 atm, the volume of 1 mol of a gas (molar volume) is 22.4 L/mol. Use dimensional analysis to calculate the volume of 0.75 mol CO at STP.
0.75 mol CO × 22.4 L/1 mol = 16.8 L = 17 L (rounded to two significant figures)
Method 2: Ideal Gas Law
Use the ideal gas law.
PV = nRT
P = pressure = 1 atm
V = volume = ? L
n = moles = 0.75 mol
R = gas constant = 0.08206 L⋅atm/K⋅mol
T = absolute temperature = 273.15 K
Solve for V.
V = nRT/P
V = (0.75 mol × 0.08206 L⋅atm/K⋅mol × 273.15 K)/(1 atm) = 16.811 L = 17 L (rounded to two significant figures)
Note: In 1982, the International Union of Pure and Applied Chemistry recommended a change of STP to 0° C (32° F, 273.15 K) and 10⁵ Pa (100 kPa). At this definition of STP, the molar volume is 22.7 L/mol, and R is 8314.5 L⋅Pa/K⋅mol (8.3145 L⋅kPa/K⋅mol).
Your instructor should indicate which values to use.
