Question

question 6 of 10 < points possible: 1.00 a student is trying to measure 5.00 ml of water with a mohr pipet. they measure the water, dispense it into a beaker, and determine the mass of the beaker + the water. the temperature in the lab is 22.0 °c. the density of water at that temperature is 0.9977 g/ml. what other piece of information does the student require in order to determine the actual volume of water that they measured? select one. more than one of the above answers is correct the volume capacity of the mohr pipet the atmospheric pressure the mass of the water they measured nothing, they have all of the information that they need

Explanation:

To determine the actual volume of water using density ($
ho=\frac{m}{V}$, where $
ho$ is density, $m$ is mass and $V$ is volume), the student already has the density of water at the given temperature and has measured the mass of the beaker + water. They need to know the mass of the empty beaker to find the mass of just the water. Then they can use the density - mass - volume relationship. Also, the volume capacity of the Mohr pipet is important as it is the tool used for dispensing the water, and atmospheric pressure can affect the accuracy of volume measurements in some cases.

Answer:

More than one of the above answers is correct
