What is molar mass?Molar mass is the weight of one mole (or 6.02 x 1023 molecules) of any chemical compounds. Molar masses of common chemical compounds that you might find in the chemistry laboratory can range between 18 grams/mole for compounds like water to hundreds of grams per mole for more complex chemical compounds.The lightest possible chemical that one can have under normal conditions is hydrogen gas‚ or H2. There is no limit to how heavy a chemical compound can be - it is not uncommon for macromolecules (large

Effects of Force and Mass on an Object’s Acceleration Abstract: In this lab there were two principals investigated. The first was the relationship between applied force and acceleration. The second was the relationship between mass and acceleration. To study these two relationships‚ my partners and I used a dynamic cart with added mass on it. This cart was then attached to a pulley system on a “frictionless track” where it was pulled by a string bearing mass over the edge of a

sheet. Show all relevant solutions neatly and state any assumptions used in solving. Box all final answers. PROBLEM NO.1 In the crank piston system shown‚ a piston P is connected to a crank AB (b 16 cm.) by a 2 kg slender rod B ( l 40 cm.). The mass of the crank AB can be considered to be very small. During a test of the system‚ crank AB is made to rotate with a constant angular velocity of 60 rad/s clockwise. There is no force applied to the face of the piston. When 60the distance between

Mass Spectrometer When you hear the words mass spectrometer‚ what do you think of? To some people‚ these words do not have any meaning; however the mass spectrometer has a great significance. The mass spectrometer has been a universal research tool‚ mostly involved in comparing the masses of atoms. Since the invention of this tool about 100 years ago‚ the mass spectrometer has been responsible for the description of molecular structure‚ the detection of isotopes‚ the classification of atomic
