Could you please help me solve the following questions?

In particular I'm looking for the formulas that help me find the solutions:

1. Ethylene glycol is used commonly as an antifreeze in automobile radiators. A 50:50 mixture of ethylene glycol and water by volume protects down to about -30F. What is the boiling points in F of this 50:50 mixture? (C2H6O2, 62.07 g/mol, 1.1132 g.mL, .94 degrees f/m, f=cx1.8+32.00)

2. How many grams carbon tetrachloride (ccl4, 153.8g./mol) are contained in a 50.0 mL flask at .756 bar and 18.00 degrees C?

3. The vapor pressure of benzene (c6hc, 78.12 g/mol) at 25 C is .1252 atm. What is the change in the vapor pressure when 10.00 g napthalene (c10h8, 128.2 g.mol) is dissolved in .2000 kg kg c6h6?
