I weighed the chalk on an electronic scale, wrote my name on the board then reweighed the chalk. It decreased from 9.27g to 9.25g. Now I have to convert it to molecules so I divided it by CaCO3's atomic mass (100.09g) and multiplied it by 6.02x10^23 and got 5.57x10^23 particles. Is this right?

My husband was in a terrible car accident about 8 years ago, he suffered a "smashed face" he aparantly has roughly about 52 screws and plates in his face. He never suffered a serious headache before then, but now he get's "cluster headache's" and these headaches he gets are so serious, that I've had to call an ambulance before. Yes of course we've been to the dr. and the Dr. want's him to see a neurologist, and he even mentioned a possible neurosurgeon? so he has an appointment in about a month. My question is what is the Neurologist going to do? what is he looking for? and why is he more qualified than the regular Dr. to help him with his headaches? One more question.. what is the job of the neurosurgeon? I am just worried about all these special titles. Should I be?

The height h (in feet) of an object that is dropped from the height of s feet is given by the formula h = s - 16t 2 , where t is the time the object has been falling. A 4 foot tall woman on a sidewalk looks directly overhead and sees a window washer drop a bottle from the 2 story. Round to the nearest tenth. (A story is 12 feet.)
