Calculation of Mass Fraction of Sodium Hydroxide

To calculate the mass fraction of sodium hydroxide in the solution obtained by mixing 40g of water and 5g of substance, we need to know the composition of the substance. Unfortunately, the search results did not provide any relevant information about the composition of the substance. Therefore, without this information, it is not possible to calculate the mass fraction of sodium hydroxide in the solution.

Determining the Density of the Solution

Similarly, the search results did not provide any information about the density of the solution obtained by mixing 40g of water and 5g of substance. Without the composition of the substance, it is not possible to determine the density of the solution.

It is important to note that in order to accurately calculate the mass fraction and density of a solution, we need to know the exact composition and properties of the substances involved.
