The weight of a metal sphere was measured to be 9.81 g. Unfortunately, the caliper that was supposed to be used in measuring the dimensions of the sphere broke. The metal that make up the sphere was identified to be an alloy of iron and chromium with a density of 7.26 g/cm3. Using the data given, calculate the radius of the metal sphere in cm. Round your answer to 2 decimal places.

A buret contains an unknown solution. mL Initially the buret was filled with the solution so that it read 12.46 mL and the balance below read 111.71 g with an 21 empty beaker on it. Some volume of the solution was dispensed into the beaker. Use the measurements from the buret and the balance to 22 determine the density of the unknown solution. d = g/mL 31.47
In an experiment a student used a 50 mL volumetric flask to prepare her copper solution but in calculations she used 100 mL as the sample volume. What effect will this error have on the final result? Will the calculated result be high of low?

How will each of the following experimental errors influence the results of your calculated densities you reported? State whether the error will tend to make your density results too large, too small or unchanged. Explain why this would occur by identifying which measurements would be affected (high or low) and how this would affect the calculated density. Use the followingIn method 2, the metal cylinder you used had a number of air bubbles on its when immersed in the water
