Question

This is a question I have for a chemistry lab and I amtrying to maintain 100% for as long as I can; however, I stumbledacross this question and I don't know what the professor is lookingfor. After doing the calculations, the final mass shouldbe
1) Q) A student obtains the mass of a beaker as 55.3224 g.S/he adds sodium chloride to the beaker and reweighs the beaker +salt. The mass is now 57.1945 g. A second beaker is placed on thebalance and the balance is set to zero. The salt from the firstbeaker is transferred into the second beaker. Which of thefollowing is the most likely mass that will be displayed on thebalance?

A) 1.8721 g
B) 55.3224 g
C) less than 1.8721 g
D) 1.8730 g

Explanation / Answer

Mass of empty   beaker , m = 55.3224g Mass of  beaker + salt , m' = 57.1945 g Mass of salt = m' - m                    =1.8721 g If the mass of salt is completely transferred into the 2 ndbeaker then the mass that will be displayed on the balance is1.8721 g If the mass of salt is not completely transferred into the 2nd beaker due to some amount is strick into the walls of the beakerthen the mass that will be displayed on the balance is lessthan 1.8721 g. If the mass of salt is not completely transferred into the 2nd beaker due to some amount is strick into the walls of the beakerthen the mass that will be displayed on the balance is lessthan 1.8721 g.
