11 A n 8 g sample of oxygen atoms contains the same number of atoms as 16 g of element x.
The question does not make sense. does it mean 11 g of A with 8 g Oxygen and 16 g X with 8 g Oxygen.

Does not make sense

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.
