The KOH is used to remove carbon dioxide by the following reaction:
KOH + CO2 KHCO3 What mass of KOH produces 235 g of KHCO3

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

a small container that holds a source of energy a solar cell that captures light energy and converts it into electricity a voltaic cell that uses the oxidation of a fuel to produce electricity

explanation:

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
