A solution is prepared by dissolving 10.60 g of ordinary sugar (sucrose, C12H22O11, 342.3 g/mol) in 47.10 g of water. Calculate the boiling point of the solution. Sucrose is a nonvolatile nonelectrolyte.

Asample of silver (with work function ? = 4.52 ev) is exposed to an ultraviolet light source (? = 200 nm), which results in the ejection of photoelectrons. what changes will be observed if: silver is replaced with copper (? = 5.10 ev) more photoelectrons ejected no photoelectrons are emitted fewer photoelectrons ejected more energetic photoelectrons (on average) less energetic photoelectrons (on average)
