Question

If 16.8 g of co is mixed under high pressure with 1.78 g of h2, what mass of methanol will be produced

(a) 1
(b) 3
(c) 5
(d) 7

Answer 1

To find the mass of methanol produced, we need to determine the limiting reactant and use the mole ratio from the balanced equation to calculate the mass of methanol.

Step-by-step explanation:

To find the mass of methanol produced, we need to determine the limiting reactant, which is the reactant that is completely consumed in the reaction. First, we need to calculate the moles of CO and H2:

1. Moles of CO = mass of CO / molar mass of CO
2. Moles of H2 = mass of H2 / molar mass of H2

Next, we need to compare the mole ratios of CO and H2 to methanol in the balanced equation:

According to the balanced equation, 1 mole of CO reacts with 2 moles of H2 to produce 1 mole of methanol.

Since the moles of H2 are in excess, the moles of CO will determine the moles of methanol produced.

Finally, we can calculate the mass of methanol:

Mass of methanol = moles of methanol x molar mass of methanol
