15 POINTS!! does anyone know the answer to this? is it A?

Answer 1

Answer:

b.2

Explanation:

Answer 2

Answer:

Mole fraction of water(H₂O) is 0.5 and the mole fraction of CH₃OH(Methanol) is 0.5.

Explanation:

Greetings !

The molecular weight of CH₃OH(Methanol)=32g/mol

The number of moles of CH₃OH=

$\frac{128g}{32g/mol}$

=4moles

The molecular weight of water H₂O =18g/mol

The number of moles of=

$\frac{72g}{18g/mol}$

=4moles

Total number of moles in the solution =4mol + 4mol

=8mol

Mole fraction Methanol CH₃OH=

$\frac{4mol}{8mol}$

=0.5mol

Hope it helps!
