Question

co(g) + 2h₂(g) → ch₃oh(g)
how many moles of ch₃oh is produced from 26 l of co at stp?
? mol ch₃oh

Explanation:

Step1: Calculate moles of CO at STP

At STP, 1 mol gas = 22.4 L. Moles of CO = $\frac{26\ \text{L}}{22.4\ \text{L/mol}}$

Step2: Relate CO to CH₃OH via stoichiometry

Reaction ratio: 1 mol CO → 1 mol CH₃OH. Moles of CH₃OH = moles of CO

Answer:

$\approx 1.16$ mol CH₃OH
