First c<span>alculate the mole fraction of each substance:
acetone: 2,88 mol </span>÷ (2,88 mol + 1,45 mol) = 0,665.
cyclohexane: 1,45 ÷ (2,88 mol + 1,45 mol) = 0,335.
Raoult's Law:
P(total) = P(acetone) · χ(acetone) + P(cyclohexane) · χ(cyclohexane).
P(total) = 229,5 torr · 0,665 + 97,6 torr · 0,335.
P(total) = 185,3 torr.
χ for acetone: 229,5 torr · 0,665 ÷ 185,3 torr = 0,823.
χ for cyclohexane: 97,6 torr · 0,335 ÷ 185,3 torr = 0,177.
Ground based reflecting telescopes uses the radio wave part of the electromagnetic spectrum to view objects.
<h3>What is a Telescope?</h3>
This is an optical instrument which makes things or objects which are far to look nearer.
Ground based reflecting telescopes are used in outer space and blocks gamma , light waves etc but uses the radio waves.

The answer is c) to repair and replace other cells.
Cell division is the replication of cells by dividing itself into two, it does not prevent replication. Cell division does not make glucose either and cell division does not make ATP.
The answer is electron.
The nucleus of a neutral potassium atom is "surrounded" by electron.
The neutral potassium atom contains equal number of protons and neutrons, and there are 19 electrons and 19 protons while 20 neutrons.
20 protons and 20 neutrons are there in the nucleus while 19 electrons surrounds the nucleus in different orbits .
