Mean will give you the average in a collected data.
The answer you're looking for is <u>D. Boiling points of various substances.</u> I got this answer because the independent variable is the thing in an experiment that is unaffected by any thing in the experiment, but has to be changed by the tester to find a change in the outcome of the dependent variable. It can't be A because depending on the temperature of the heated container must be different to reach the boiling point of different substances, for this reason, we also find out that D is the answer. I hope that this helps!
Answer:
1. Gases can be easily liquefied into very small volumes and stored in liquid form Eg in LPGA cylinders and used in homes.
2. Balloons can be easily filled with air.

Answer: <u>Molarity of solution is 0.751 M. </u>
Reason:
Given: weight of solute (LiF) = 17.8 g, volume of solution = 915 ml = 0.915 l
We know that,
Molarity = </span>

<em>Molecular Weight of LiF = 25.9 g/mol. </em>
</span>∴<span>,
Molarity = </span>
<span> =
0.751 M</span>
