Which is more concentrated, a solution containing 10g of NaCl in 100 g
of water OR a solution containing 10 g of NaCl in 90 g of water? How do
you know your answer is correct?
help!!!

The answer is the solution containing the 90g of water.

Explanation:

Because both solutions have the same amount of the sodium chloride, the concentration would be the same if they both had the same amount of water.

Because the second solution has less water, there is more of the sodium chloride per each drop of water.

I hope this helps :)

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
