Chloroform, CHCl3, has a density of 1.492 g/mL and a molar mass of 119.38 g/mol. (PLEASE DON’T ANSWER IF YOU CAN’T SHOW YOUR WORK OR GIVE AN EXPLANATION I’M REALLY TRYING TO LEARN HOW TO DO THIS) How much volume in mL does each mol of CHCl3 occupy? Hint: “Each mol” is
an exact amount and has infinite number of sig figs.

How many mol are there in 100.0 mL of CHCl3?

If the atomic mass of an atom is 34 and the atom contains 13 protons, how many neutrons does the atom contain?

Agroup of students is studying convection current. they fill two identical balloons with the same amount of helium. one balloon is placed in a freezer and the other is in an area with warm air. after 10 minutes, the balloon are released from a height of 1 meter. which of the following to the students most likely observe? a) the warm balloon expands and rises. the cold balloon shrinks and sinks b) the balloon both rise. the cold balloon is larger than the warm balloon c) the cold balloon expands and rises. the warm balloon shrinks and sinks d) the balloon rise at the same rate. both balloons are the same size
