Question

Suppose that a student performing this experiment did not remove ALL the air bubbles in the micropycnometer when filling it with their liquid unknown. Assuming there were no other errors, would the density of the liquid unknown be high, low, or unaffected by the error?

Suppose that a student performing this experiment did not remove ALL the air bubbles in the micropycnometer when filling it with water. Assuming there were no other errors, would the density of the liquid unknown be high, low, or unaffected by the error?

Explanation / Answer

Q1

if there are some bubbles, then the total V of the device will be higher

then

D = mass/V

D depends inversely to V

if V increases,

Density will be LOWER than the real value

Q2

The volume of water accounts higher than the real value

when claculating the Volume of water displaced

it wil lbe LOWER

therefore

Volume of unkownn = lower

Density = inversley proportional

Density increases for the unkown
