calculate the molarity in a 0.550 m solution of NaCl in water. Assume that the solution density is 1.03g/mol
Anarel [89]

Answer:

M=0.549M

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to perform this calculation by firstly assuming we have 1 kg of water as the solvent so that we have 0.550 moles of NaCl as well. Moreover, we realize we have 1000 grams of water and the correct mass of the solution can be calculated by converting 0.550 moles of NaCl to grams by using its molar mass:

m_{solute}=0.550mol*\frac{58.44 g}{1mol}= 32.14g\\\\m_{solution}=1000g+32.14g=1032.14g

And subsequently, the volume in liters by using the density and the correct conversion factor:

V_{solution}=1032.14g*\frac{1mL}{1.03g} *\frac{1L}{1000mL} =1.002L

Finally, the molarity will be:

M=\frac{0.550mol}{1.002L} =0.549M

Regards!

According to the kinetic-molecular theory, what is one way the three states of matter are all similar?
Delicious77 [7]

The kinetic molecular theory of matter states that:

1. Matter is made up of particles that are constantly moving.

2. A change in phase may occur when the energy of the particles is changed.

3. All particles have energy, but the energy varies depending on the temperature the sample of matter is in. This in turn determines whether the substance exists in the solid, liquid, or gaseous state.
