Question

Pls try 12 and send sol also

Answer 1

Answer:

The mole fractions of ethanol and water are 0.25 and 0.75 bhai

Explanation:

Molar mass of C₂H₅OH (ethanol) is: 46

Molar mass of H₂O (water) is: 18

So, mass of ethanol= 0.25 x 46= 11.5g

and mass of water= 0.75 x 18 = 13.5g

So, now, $\frac{11.5}{11.5 + 13.5}$ x 100% = 11.5 x 4 = 46% option 3 hai bhai..

pls mark me brainliest
