What is the molarity of 125 ml of solution containing 5.31 g sodium nitrate​

Chemistry
1 answer:
quester [9]3 years ago

<h3>Answer:</h3>

0.5 moles/L or 0.5 M

<h3>Explanation:</h3>
  • Molarity is the concentration of a solution in moles per liter.
  • It is calculated by;

Molarity = Number of moles ÷ Volume

In this case;

Volume = 125 mL

Mass of sodium nitrate = 5.31 g

We are required to calculate the molarity of sodium nitrate

<h3>Step 1: Calculate the number of moles of sodium nitrate </h3>

Moles = Mass ÷ Molar mass

Molar mass of sodium nitrate = 84.9947 g/mol

Therefore,

Moles of NaNO₃ = 5.31 g ÷ 84.9947 g/mol

                            = 0.0625 moles

<h3>Step 2: Molarity of sodium nitrate </h3>

Remember;

Molarity = Moles ÷ Volume

Volume of NaNO₃ = 0.125 L

Therefore;

Molarity = 0.0625 moles ÷ 0.125 L

            = 0.5 Moles/L or 0.5 M

Thus; the concentration of sodium nitrate is 0.5M

Why does a bouncing ball rise to a lower height with each bounce
patriot [66]
Gravity is one major part of that thing because gravity wants to pull down on things. Another part of it is the kinetic/potential energy because with each bounce it goes lower the less kinetic energy it has.

How do you convert ethane to ethanoic acid? (with equation please).
Bess [88]
Ethane can be turned into its carboxylic acid form called the ethanoic acid by a series of steps. First chlirinate it in the presence of light. Then, add potassium hydroxide to get an alcohol. Finally, adding KMnO4 to oxidize it to a carboxylic acid. The equations are as follows:
C2H6 + Cl2  ---> C2H5Cl + HCl
C2H5Cl+KOH-> C2H5OH+ KCl.
C2H5OH  ----KMnO4 ---> CH3COOH.

goldfiish [28.3K]

Answer:

Just study the thing don't expect others to just answer the homework for you

Explanation:

If you truly are a good student then you should have asked your teacher in person or through email instead of asking on here. Not trying to be mean but you also have to understand that people on here have a life. :)

When 91.5 g of isopropyl alcohol which has an empirical formula of C3H8O is burned in excess oxygen gas, how many grams of H2O a
Kobotan [32]

Answer:

109.7178g of H2O

Explanation:

First let us generate a balanced equation for the reaction. This is illustrated below:

2C3H8O + 9O2 —> 6CO2 + 8H2O

Next we will calculate the molar mass and masses of C3H8O and H20. This is illustrated below:

Molar Mass of C3H8O = (3x12.011) + (8x1.00794) + 15.9994 = 36.033 + 8.06352 + 15.9994 = 60.09592g/mol.

Mass of C3H8O from the balanced equation = 2 x 60.09592 = 120.19184g

Molar Mass of H2O = (2x1.00794) + 15.9994 = 2.01588 + 15.9994 = 18.01528g/mol

Mass of H2O from the balanced equation = 8 x 18.01528 = 144.12224g

From the equation,

120.19184g of C3H8O produced 144.12224g of H20.

Therefore, 91.5g of C3H8O will produce = (91.5 x 144.12224) /120.19184 = 109.7178g of H2O
