Question

Assume that you have two graduated cylinders, one with a capacity of 5 mL (a) and the other with a capacity of 50 mL (b). Draw a line in each, showing how much liquid you would add if you needed to measure 2.64 mL of water. Which cylinder will give the more accurate measurement? Explain.

Hi everyone for this problem. It reads Shawn below are a 10 millimeter graduated cylinder and a five millimeter graduated pipette. You are supposed to measure out 3.7 mL of water. Which tool will provide the more accurate measurement. Okay, so we want to know out of these two which one will provide the more accurate measurement. And let's recall that accuracy is close to true value. So we want to know out of the two which one is going to give us a close to true value of 3.7 mL of water. So let's go ahead and take a look and we have three answer choices. All right. So for the 10 millimeter graduated cylinder on the left, it's marked at every 0.2 mil leaders. The pipette is marked at every 0.1 male leader. So in terms of reading this, the cylinder is going to be read at plus or -0.02 male leaders. And the pipette is going to be read at plus or -0.01 ml. Okay with this we can see since we're looking for which one is going to be more accurate or close to true value. The graduated pipette will provide a more accurate measurement because it is only plus or minus 0.1 mL. Okay, so that's going to make answer choice B Our correct answer here. Okay, Because we're looking for accuracy and we're looking for what is going to give us the close to true value. Alright, so that is it for this problem. I hope this was helpful
