mole fraction of potassium bromide = 0.23

Explanation:

We define mole fraction of a specific compound in a mixture as:

mole fraction of a compound = number of moles of the compound / total number of moles

in our case we have:

number of moles of potassium bromide = 3 moles

total number of moles = number of moles of potassium bromide + number of moles of water

total number of moles = 3 + 10 = 13 moles

mole fraction of potassium bromide = 3 / 13 = 0.23

Why are summer days longer than winter days on Earth?
zimovet [89]

Answer:

A. During the summer, Earth's rotational axis is parallel to the Sun's rotational axis.

Explanation:

Actually, though, the Earth is tilted 23.4 degrees! (A circle is 360 degrees.) This tilt is the reason that days are longer in the summer and shorter in the winter. The hemisphere that's tilted closest to the Sun has the longest, brightest days because it gets more direct light from the Sun's rays.

Plz mark me brainliest if correct :)
