assume that a drop has a volume of o.o5 ml. if a titration requires 30.00 ml for completion, what % error will each extra drop over 30 ml cause?
is it 30.05-30 divided by 30 then times 100 which is equal to 0.17 %
Yes. (0.05/30)*100 = ?
Well, you're almost there! Since each extra drop over 30 ml is 0.05 ml, you can calculate the percentage error as follows:
(0.05 ml / 30 ml) * 100
This gives you a percentage error of approximately 0.17%. Good job on your math skills! Just remember, in the grand scheme of things, that's a pretty tiny error. I mean, it's like finding a sprinkle of glitter in a sandbox.
To calculate the percent error caused by each extra drop over 30 ml, you would use the following formula:
Percent Error = ((Volume of Extra Drops - Desired Volume) / Desired Volume) x 100
In this case, the desired volume is 30.00 ml and the volume of each drop is 0.05 ml. Let's calculate the percent error for each extra drop:
Percent Error = ((0.05 ml - 30 ml) / 30 ml) x 100
Percent Error = (-29.95 ml / 30 ml) x 100
Percent Error = -0.9983 x 100
Percent Error = -99.83%
So, each extra drop over 30 ml would contribute a percent error of approximately -99.83%.
To calculate the percentage error caused by each extra drop over 30 ml, you need to determine the difference between the actual volume and the desired volume, and then calculate it as a percentage of the desired volume.
1. Determine the desired volume: The titration requires 30.00 ml.
2. Determine the actual volume: Each drop has a volume of 0.05 ml. If the titration requires 30.00 ml for completion, any additional drops will contribute to the actual volume.
3. Calculate the difference between the actual and desired volume: Subtract the desired volume (30.00 ml) from the actual volume taking into account any extra drops.
For example, if there are 5 extra drops, the actual volume would be 30.00 ml + (5 drops x 0.05 ml/drop) = 30.25 ml
So, the difference would be 30.25 ml - 30.00 ml = 0.25 ml
4. Calculate the percentage error: Divide the difference by the desired volume and multiply by 100 to get the percentage.
Percentage error = (0.25 ml / 30.00 ml) x 100
Simplifying, the percentage error is approximately 0.83% (not 0.17%).
Therefore, each extra drop over 30 ml will cause a percentage error of approximately 0.83%.
