5.0 x 10 ^1 mL
Explanation:
M1V1 = M2V2
(0.25 M) (400 mL) = (2.0 M) V2
Divide both sides by 2.0 M
V2 = (0.25 M*400mL)/2.0 M
Molarity’s cancel out
V2 = 5.0 x 10^1 mL

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.
