Answer from: emilyturchon

9.01%

Explanation:

The following data were obtained from the question:

Mass of sodium nitrate, NaNO3 = 56.5g

Mass of solution = 627g

The percentage composition of sodium nitrate, NaNO3 in the solution can be obtained as follow:

Percentage composition of NaNO3 = Mass of NaNO3/mass of solution x 100

Percentage composition of NaNO3 = 56.5/627 x 100 = 9.01%

Therefore, the percentage composition of sodium nitrate, NaNO3 in the solution is 9.01%

Answer from: cynthiakk

The percentage of sodium nitrate in the solution is 9.01%

Explanation:

Here we have;

56.5 g of sodium nitrate dissolved in water to make a solution of mass = 627 kg

Mass of sodium nitrate, NaNO₃, in the solution = 56.5 g

Mass of resultant solution = 627 g

The relation for the percentage of a solute by mass dissolved in a solvent is presented as follows;

$Percentage \, by \, mass = \frac{Mass \, of \, solute}{Mass \, of \, solution} \times 100$

Therefor, for the 56.5 g of sodium nitrate solution, we have;

$Percentage \, by \, mass \, of \, NaNO_3 = \frac{Mass \, of \, NaNO_3}{Mass \, of \, solution} \times 100 = \frac{56.5 \, g}{627 \, g} \times 100 = 9.01 \%$

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.

In a laboratory determination of the atomic weight of tin, a sample of tin is weighed in a crucible. nitric acid is added, and the reaction proceeds to give a hydrated tin(iv)oxide plus no2and h2o. the hydrated tin(iv)oxide is then heated strongly and reacts as follows: sno2.xh2o(s)sno2(s)+ xh2o(g)the sno2is finally cooled and weighed in the crucible. explain the effect on the calculated atomic weight of tin that would result from each of the following experimental errors: (a)considerable spattering occurs when the nitric acid is added to the tin.(b)the hydrated tin(iv)oxide is not heated sufficiently to change it completely to tin oxide.
