Question

Draw the graph of each of the following linear equations in two variables:
(i) y= 3x
(ii) 3 = 2x +y​

Answer 1

Answer:

Number of moles of C₂H₅OH=Given mass/Molar mass.

Mole fraction of C₂H₅OH=Number of moles of C₂H₅OH/Number of moles of solution.

Mole fraction of C₂H₅OH=1/5+1=1/6=0.16.Number of moles of C₂H₅OH=Given mass/Molar mass.

Mole fraction of C₂H₅OH=Number of moles of C₂H₅OH/Number of moles of solution.

Mole fraction of C₂H₅OH=1/5+1=1/6=0.16.

Answer 2

3 = 2x + y

2x + y =3

y = 3 - 2x

hope this helps you
