Calculate the number of carbon atoms in a 50.0 g sample of camphor (C10H160). Be sure your answer has a unit symbol if necessary, and round it to 3 significant digits. x10 X 5

Q2- Find the percentage of aspirin if you know that the weight of salicylic acid is 1 gm and the practical weight of aspirin is 0.8

In the picture below, determine how many atoms with a radius of 37pm can fit into a 1.00" box. Canvas does not work well with scientific notation, so you should enter your number as a regular number (you might have lots of zeros, hint, hint). So if you found the answer was 6.36x106 atoms, then you would write 6360000. Hint: Do this as a conversion and start with 1.00 inch as your starting number. This problem seems much more complicated, but it is the same problem you have been doing, you just need to make the units match! r=37pm 1.00"

3/5 Calculate the number of hydrogen atoms in a 90.0 g sample of camphor (C10H160). Be sure your answer has a unit symbol if necessary, and round it to 3 significant digits. x10
