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

hurry please! avogadro's law relates the volume of a gas to the number of moles of gas when temperature and pressure are constan
DIA [1.3K]

Answer:

Option B. 4 moles of the gaseous product

Explanation:

Data obtained from the question include:

Initial volume (V1) = V

Initial number of mole (n1) = 2 moles

Final volume (V2) = 2V

Final number of mole (n2) =..?

Applying the Avogadro's law equation, we can obtain the number of mole of the gaseous product as follow:

V1/n1 = V2/n2

V/2 = 2V/n2

Cross multiply

V x n2 = 2 x 2V

Divide both side by V

n2 = (2 x 2V)/V

n2 = 2 x 2

n2 = 4 moles

Therefore, 4 moles of the gaseous product were produced.

Does methylenecyclohexane obey Zaitsev's rule? why or why not
kifflom [539]

Answer:

Explanation: Zaitsev’s or Saytzev’s (anglicized spelling) rule is an empirical rule used to predict regioselectivity of 1,2-elimination reactions occurring via E1 mechanism or via E2 mechanism. It states that in a regioselective E1 or E2 reaction the major product is the more stable alkene, i.e., the alkene with the more highly substituted double bond.

E1 reaction always follow Zaitsev’s rule; with E2 reactions, there are exceptions (see antiperiplanar).
