What is the osmolarity of .00001 grams (0.1 mg%) of ethanol (does not dissociate) in one liter?

MrMuchimi

Explanation:

As it is known that non-electrolytes do not dissociate. Therefore, molarity of such a solution is equal to the osmolarity of solution.

As, molar mass of ethanol = 46.07 g/mol

Therefore, no. of moles of ethanol will be calculated as follows.

No. of moles = $\frac{mass}{\text{molar mass}}$

= $\frac{0.00001 g}{46.07 g/mol}$

= $2.17 \times 10^{-7}$ mol

As, molarity is moles of solute in liter of solution. Hence, molarity of ethanol is as follows.

Molarity = $\frac{\text{no. of moles}}{volume}$

= $\frac{2.17 \times 10^{-7} mol}{1 L}$

= $2.17 \times 10^{-7}$ mol/L

Since, for the given solution Molarity = osmolarity

Thus, we can conclude that osmolarity of .00001 grams (0.1 mg%) of ethanol in 1 L is $2.17 \times 10^{-7}$ osmol/L.

A student added 500 mL of water to 200 mL of 0.20M NaCl solution. Which of the following is True?

tamaranim1 [39]

Option B is true , the same number of moles of solute in both solution is the same.

<h3>What is Molarity? </h3>

Molarity is the ratio of no of moles as per liter solution. It is denoted by M and SI unit is also M or moles/litre.

Molarity = no . Of moles/Volume (L)

In this question the amount of solution is increased means the volume is increased from 500-700ml it is increased , Molarity is inversly proportional of Volume

it will decrease if volume increase. Adding water do affect the concentration of the solution. The no. Of moles of solute remains because there no increament in amount of NaCl .

Hence ,option B is more correct
