Question

Calculate the amount of concentrated trioxonitrate V acid, 18moldm-3 which is requires to prepare 5.0dm3 of 2.0moldm-3 trioxonitrate V acid. Convert your final answers to cubic centimeters

Answer 1

To calculate the amount of concentrated trioxonitrate V acid needed, we can use the formula:

C1V1 = C2V2

Where:
C1 is the concentration of the concentrated acid (18 mol/dm^3)
V1 is the volume of the concentrated acid needed
C2 is the desired concentration of the final solution (2 mol/dm^3)
V2 is the final volume of the solution (5 dm^3)

Rearranging the formula to solve for V1:

V1 = (C2V2)/C1

V1 = (2 mol/dm^3 * 5 dm^3) / 18 mol/dm^3
V1 = 10/18
V1 = 0.5556 dm^3

To convert the volume from dm^3 to cm^3, we multiply by 1000:

V1 = 0.5556 dm^3 * 1000 cm^3/dm^3
V1 = 555.6 cm^3

Therefore, the amount of concentrated trioxonitrate V acid required is 555.6 cm^3.

Answer 2

Let me point out that trioxonitrate V acid is not the name of choice for nitric acid, HNO3.

Answer 3

Apologies for the confusion. You are correct that trioxonitrate V acid is not the common name for nitric acid, HNO3. In that case, let's calculate the amount of nitric acid needed.

Using the same formula:

C1V1 = C2V2

Where:
C1 is the concentration of the concentrated acid (18 mol/dm^3)
V1 is the volume of the concentrated acid needed
C2 is the desired concentration of the final solution (2 mol/dm^3)
V2 is the final volume of the solution (5 dm^3)

Rearranging the formula to solve for V1:

V1 = (C2V2)/C1

V1 = (2 mol/dm^3 * 5 dm^3) / 18 mol/dm^3
V1 = 0.5556 dm^3

To convert the volume from dm^3 to cm^3, we multiply by 1000:

V1 = 0.5556 dm^3 * 1000 cm^3/dm^3
V1 = 555.6 cm^3

Therefore, the amount of nitric acid (HNO3) required is 555.6 cm^3.
