Homework Help: college chemistry

Posted by dancechick123 on Monday, January 28, 2013 at 9:38am.

calculate the specific heat for 18.5-g sample of tin that absorbs 183 J when its temp increases from 35.0 degrees celcius to 78.6 degress celcius. I don't know where to even start, help?

Note the correct spelling of celsius.
q = mass Sn x specific heat x (Tfinal-Tinitial)
183 = 18.5g x sp.h. x (78.6-35.0)
Solve for sph.

The distance between the centers of two atoms in a diatomic molecule is 1.22 angstroms. (An angstrom is 10-10 m.) Calculate the distance in feet.
