Question

The KOH is used to remove carbon dioxide by the following reaction:
_________KOH + __________CO2 ________KHCO3 What mass of KOH produces 235 g of KHCO3

Answer 1

Answer:

131.86g

Explanation:

KOH + CO2 => KHCO3

Molar mass of KHCO3 = 100.115g/Mol

No of mole = 235/100.115 = 2.35mole

1mole of KOH will give 1 mole of KHCO3

Xmole of KOH will give 2.35mole of KHCO3

X= 2.35mole of KOH

No of mole of KOH = mass/molar mass

2.35= mass/56.11

Mass= 131.86g
