Hello,
In this case, for the mole fraction of methanol we use the formula:
Thus, we compute the moles of both water (molar mass 18 g/mol) and methanol (molar mass 32 g/mol):
Hence, mole fraction is:
Next, mass percent is:
And the molality, considering the mass of water in kg (0.185 kg):
Regards.
Answer:
Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. The plates act like a hard and rigid shell compared to Earth's mantle. ... The lithosphere includes the crust and outer part of the mantle.
Explanation:
The minimum would be 0 degrees Celsius or 32 degrees Fahrenheit.
