Astudent took a calibrated 200.0 gram mass, weighed it on a laboratory balance, and found it read 186.5 g. what was the student’s percent error?

The original or accepted value for the percent by mass of water in a hydrate = 36%

Percen by mass of water in the hydrate determined by the student

in the laboratory = 37.8%

So the difference between the actual and the percent by mass in water determined by student = (37.8 - 36.0)%

            = 1.8%

So the percentage of error made by the student = (1.8/36) * 100 percent

                                                                            = (18/360) * 100 percent

                                                                            = ( 1/20) * 100 percent

                                                                             = 5 percent

So the student makes an error of 5%. Option "1" is the correct option.

Explanation:

i wanna say it’s between b and d, leaning more towards b.

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
