Give me handwritten answer 

1. Methyl alcohol, CH,OH, has a normal boiling point of 64.7 °C and has a vapor
pressure of 203 mmHg at 35 °C. Calculate
a) its heat of vaporization (AHapor)
b) its vapor pressure at 40.0 °C.
2. For each of the following pairs , choose the member with the lower boiling point:
a) CO, or SO2
b) HBr or HCI
c) H, or O,
d) F, or Cl
3. Consider the CsCl cell (Fig. 9.18). The ionic radii of Cs* and Cl are 0.169 and 0.181
nm, respectively. What is the length of
a) the body diagonal ?
b) the side of the cell ?
4. The Henry's law constant for the solubility of oxygen in water is 3.30 x 10 M/atm
At 12 °C and 2.85 x 10 M/atm at 22 °C. Air is 21 mol% oxygen.
How many grams of oxygen can be dissolved in a liter of a trout stream at 12 °C at
an air pressure of 1.00 atm ?
5. A compound containes 42.9% C, 2.4% H, 16.6% N, and 38.1% O. The addition of
3.16 g of this compound to 75.0 mL of cyclohexane (d = 0.779 g/cm3) gives a
solution with a freezing point at 0.0 oC. Using Table 10.2, determine the molecular
formula of the compound.
