We need to prepare 500. ml of 1.00M acetic acid from a 17.4M stock solution. What volume of stock solution is required
500 mL of 1M = 0.5 moles of solute
0.5 mole / (17.4 mole/L) = 0.5/17.4 = 0.0287 L
so, take 28.7 mL of the stock and fill with water to 500mL
Well, let's do some "acetic" math, shall we?
To prepare a 1.00M acetic acid solution, we'll need to dilute the 17.4M stock solution. The relationship between the two solutions can be written as:
C1V1 = C2V2
Where C1 and V1 are the concentration and volume of the stock solution, and C2 and V2 are the concentration and volume of the final solution. We can rearrange the equation to solve for V1:
V1 = (C2V2) / C1
Plugging in the given values, we have:
V1 = (1.00M * 500ml) / 17.4M
Calculating that out, the volume of the stock solution required would be approximately 28.74ml.
So, you'll need to measure out 28.74ml of the stock solution to prepare your desired 500ml of 1.00M acetic acid solution. Happy dilutions!
To prepare 500 ml of 1.00M acetic acid from a 17.4M stock solution, you can use the following formula:
(C1)(V1) = (C2)(V2)
where:
C1 = concentration of the stock solution in M (17.4M)
V1 = volume of the stock solution needed in ml (unknown volume)
C2 = desired concentration of the final solution in M (1.00M)
V2 = desired volume of the final solution in ml (500 ml)
Substituting the values into the formula:
(17.4M)(V1) = (1.00M)(500ml)
Solving for V1:
V1 = (1.00M)(500ml) / (17.4M)
V1 = 28.74 ml
Therefore, you would need to measure 28.74 ml of the 17.4M stock solution to prepare 500 ml of 1.00M acetic acid.
To find the volume of the stock solution required, we can use the formula:
C1V1 = C2V2
Where:
C1 = concentration of the stock solution (17.4 M)
V1 = volume of the stock solution (unknown)
C2 = concentration of the desired dilution (1.00 M)
V2 = volume of the desired dilution (500. ml or 0.500 L)
Rearranging the formula, we have:
V1 = (C2 x V2) / C1
Now we can substitute the values into the formula and solve for V1:
V1 = (1.00 M x 0.500 L) / 17.4 M
V1 = 0.0287 L
To convert this volume from liters to milliliters, we multiply by 1000:
V1 = 0.0287 L x 1000 ml/L
V1 = 28.7 ml
Therefore, you would need approximately 28.7 ml of the stock solution to prepare 500 ml of 1.00 M acetic acid.
