Answer to Question #80537 in General Chemistry for Halima Tokhi

Question

The following data are collected in determining the accuracy of a 25 mL pipet:

Value Units
Temperature of Water 18.1 oC
Density of Water (from Table) 0.99899 g/mL
Weight of Empty Beaker 57.78 g
Weight of Beaker + Sample 1 82.94 g
Weight of Beaker + Sample 1 + Sample 2 108.07 g
Question 6
We can test how accurately a person is using the pipet by calculating the volume of water they deliver with it. The calculated volume should be equal, or very close, to 25 mL if the person used the pipet correctly. The volume of a sample of water delivered from the pipet is calculated from the mass of this water, along with the density of water at room temperature.



The calculated volume (from the mass and density) of Sample 1 of water delivered with the pipet is 25.19 mL. What is the calculated volume of Sample 2 in mL?

Enter your answer to the correct number of significant figures.

Do not include units with your answer.
