How much methanol (ch3oh, in grams) can be formed from 42.2 kg of hydrogen? assume excess co. co(g) + 2h2(g) → ch3oh(g)

335 000 g

Explanation:

We know that we will need a chemical equation with masses and molar masses, so let’s start by gathering all the information in one place.

:                2.016       32.04

                 CO + 2H₂ ⟶ CH₃OH

Mass/kg:            42.2

1. Use the molar mass of H₂ to calculate the moles of H₂.

Note: 1 g/mol ≡ 1 kg/kmol

2. Use the molar ratio of CH₃OH:H₂ to calculate the moles of CH₃OH.

3.Use the molar mass of CH₃OH to calculate the mass of CH₃OH.

let that person have a turn to speak : )
