The mole fraction of co2 in a certain solution with h2o as the solvent is 3.6 × 10−4. what is the approximate molality of co2 in this solution? a.0.00036 m. b.0.0065 m. c.0.020 m. d.2.0 × 10−5 m. e.6.5 m

C) 0.020 m

Explanation:

Molality of a solution is defined as the number of moles of solute dissolved per kg of the solvent.

where,

n = moles of solute  

= weight of solvent in g  

Mole fraction of is = i.e.  moles of is present in 1 mole of solution.

Moles of solute =

moles of solvent (water) = 1 - = 0.99

weight of solvent =

Molality =

Thus  approximate molality of in this solution is 0.020 m

you gotta add the following molecules so we can give u an answer
