Find the molarity of 0.50 l solution containing 9.0 g nacl

Chemistry
1 answer:
levacccp [35]2 years ago
8 0

Answer: 0.31 moles/L

Explanation:

<u>Given:</u>

Mass of NaCl = 9 g

Volume of Solution = 0.50 L

Molarity: ?

The formula used to calculate Molarity is:

Molarity (M) = Number of moles of solute / Volume of solution in litres

<u>We know,</u>

Number of Moles = Given mass / molar mass

<u>So,</u>

Moles of HCl

= 9 g / (58.44 g/mol )

= 0.154 moles

<u>Therefore,</u>

Molarity

= 0.154 moles / 0.50 L

= 0.31 moles/L

A neutral atom of which of the four element has the smallest radius
arsen [322]
Answer:
Element 1

Explanation:
The ionization energy is defined as the energy required to remove electrons from the atoms.
We know that the nucleus of the atom attracts the electrons, thus, bound these electrons to the atom.
This means that as the radius decreases, the force of attraction between the nucleus and the electron will increase, therefore, the energy required to remove the electron would increase (and vice-versa).

Based on the above, the atom with the smallest radius would be the atom with the largest first ionization energy.

Hope this help :)

What causes hurricanes in the northern hemisphere to roster counterclockwise ?
Andrew [12]

Answer: The answer is D.

Explanation:

As the air rushes toward the center, it winds up moving in a curved path thanks to the Coriolis effect. This creates a circular spinning pattern as air travels from areas of high pressure to low pressure. That's why hurricanes originating in the northern hemisphere rotate counterclockwise.

Hope this helps!
