The initial water level, before inserting shaped solid, is 30.0 ml. After inserting the solid, the ml is used in a density the irregular water level is 32.5 ml. i. What is the probable error in the volume of the solid? 2 What is the probable percent error in the volume of the solid? 2 A lab class conducts a 1000 trial scattering probability experiment. Nine (9) target marbles were used on a 45.0 cm wide board. The marble diameter was calculated to be 1.48 cm How many hits were recorded during the If the standard value for the marble diameter is 1.55 cm, what is the probable percent erro diameter? r in the experimental marble

Explanation / Answer

Solution: The initial water level was 30.0 ml. When the solid is inserted in the cylinder, new water level is at 32.5 ml. Thus the solid has an volume of (32.5 – 30)ml = 2.5 ml.

Part 1) The graduated cylinder has the least count of + 0.5 ml. It means that the true volume of the inserted solid lies between (2.5 – 0.5)ml = 2.0ml and (2.5+0.5)ml = 3.0 ml.

Thus the probable error is + 0.5 ml

---------------------------------------------------------------------------------------------------------------------------------------------

Part 2) Probable percentage error is (0.5 ml)/(2.5ml)*100 = 20%

Thus the probable percentage error is 20%
