Answer:

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:

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 \%

What do you think happens to the bonds between atoms when substances melt?
Eduardwww [97]

Answer:

As a substance melts, and goes from a solid to a liquid state, the kinetic energy of the molecules increases, and the molecules move faster, and they separate further and further away from each other.  The intermolecluar forces holding the molecules together become weaker.  This is why a liquid can take fill the shape of its container, whereas a solid has a fixed shape.

Draw the Lewis structure for methane (CH4) and ethane (C2H6) in the box below. Then predict which would have the higher boiling
Alinara [238K]

Answer:

Ethane would have a higher boiling point.

Explanation:

In this case, for the lewis structures, we have to keep in mind that all atoms must have <u>8 electrons</u> (except hydrogen). Additionally, each carbon would have <u>4 valence electrons</u>, with this in mind, for methane we have to put the hydrogens around the carbon, and with this structure, we will have 8 electrons for the carbon. In ethane, we will have a bond between the carbons, therefore we have to put three hydrogens around each carbon to obtain 8 electrons for each carbon.

Now, the main difference between methane and ethane is an <u>additional carbon</u>. In ethane, we have an additional carbon, therefore due to this additional carbon, we will have <u>more area of interaction</u> for ethane. If we have more area of interaction we have to give <u>more energy</u> to the molecule to convert from liquid to gas, so, the ethane will have a higher boiling point.

I hope it helps!
