Question

Problem 2. A student measures the mass of 49.4 cc of water and finds the mass to be 50.2 g. Assume that the accepted value is 1.00 g/cc. Compute the density of the water and the percent deviation. Computed Density = Percent Deviation Remember to include the units with the density. Note: If you did these problems correctly, your value of density should have agreed With the expected value to within four percent, n Problem 1. In Problem 2. on the other hand, agreement is good to within two percent.

Explanation / Answer

Note that

D = M/V

where M = mass, V = volume. Thus,

Computer density = 50.2 g/49.2 cc

= 1.016 g/cc   [ANSWER]

********************

Percent deviation = [obtained - actual] / actual * 100%

As obtained density = 1.016 g/cc, actual density = 1.00 g/cc,

Percent deviation = 1.6%   [ANSWER]
