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
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.
Let me point out that trioxonitrate V acid is not the name of choice for nitric acid, HNO3.
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.
To calculate the amount of concentrated trioxonitrate V acid required, we can use the formula:
C1V1 = C2V2
where C1 is the initial concentration, V1 is the initial volume, C2 is the final concentration, and V2 is the final volume.
Given:
C1 = 18 moldm-3
V1 = unknown
C2 = 2 moldm-3
V2 = 5.0 dm3
Rearranging the formula, we have:
V1 = (C2 * V2) / C1
Substituting the values:
V1 = (2 * 5.0) / 18
V1 ≈ 0.5556 dm3
To convert the answer to cubic centimeters, we can use the conversion factor: 1 dm3 = 1000 cm3.
Converting:
V1 = 0.5556 dm3 * 1000 cm3/dm3
V1 = 555.6 cm3 (rounded to one decimal place)
Therefore, approximately 555.6 cm3 of concentrated trioxonitrate V acid is required to prepare 5.0 dm3 of 2.0 moldm-3 trioxonitrate V acid.
