The kind of energy that is released is called NUCLEAR ENERGY.

Nuclear energy refers to the energy that is released from a radioactive element as a result of decay of the nucleus of that element. An atom is made up of three sub particles, which are proton, neutron and electrons. The proton and the neutron are located in the nucleus of the element while the electron is located at the outside of the nucleus. Radioactive elements usually undergo spontaneous decay and during the process a lot of energy is released, this energy is called nuclear energy because it comes from the decay of the nucleus of the atom of the element. Nuclear energy can be obtained as a result of nuclear fusion or nuclear fission and the energy can be used to do a lot of things such as generation of electricity.

Which of the following gives the molarity of a 17.0% by mass solution of sodium acetate, CH 3COONa (molar mass = 82.0 g/mol) in
weeeeeb [17]

Answer:

The molarity of this solution is 2.26 M (option D)

Explanation:

Step 1: Data given

Mass % = 17%

Molar mass of CH3COONa = 82.0 g/mol

Density of the solution = 1.09 g/mL

Step 2:

Assume the mass of the solution is 1.00 gram

⇒ 17.0 % CH3COONa = 0.17 grams

⇒ 83.0 % H2O = 0.83 grams

Step 3:

Density = 1.09 g/mL

Volume of the solution = total mass / density of solution

Volume of solution : 1.00 grams / 1.09 g/mL

Volume of the solution = 0.917 mL = 0.000917 L

Step 4: Calculate  number of moles of CH3COONa

Number of moles = Mass / molar mass

Number of moles CH3COONa = 0.170 grams / 82.0 g/mol

Number of moles = CH3COONa = 0.00207 moles

Step 5: Calculate molarity

Molarity = moles / volume

Molarity solution =   0.00207 / 0.000917 L

Molarity solution =  2.26 mol/L = 2.26 M

The molarity of this solution is 2.26 M (option D)
