The volume V of an ideal gas varies directly with the temperature T and inversely with the pressure P. A cylinder contains oxygen at a temperature of 310 degrees K and a pressure of 18 atmospheres in a volume of 120 liters. Find the pressure if the volume is decreased to 105 liters and the temperature is increased to 350 degrees K.

Round your answer to two decimal places.

How would you prepare 1.00 L of a 0.50 M solution of each of the following,

a) H₂SO₄ from concentrated (18 M) sulfuric acid

b) HCl from concentrated 12 M reagent

c) NiCl₂ from salt NiCl₂.6H₂O

d) HNO₃ from concentrated 16 M reagent

e) Sodium carbonate from pure solid

How would you prepare 1.00L of a 0.50-M solution of each of the following?

a.  from "concentrated" (18M) sulfuric acid

b. HCl from "concentrated" (12M) reagent

c. from the salt  

d. from "concentrated" (16M) reagent

e. Sodium carbonate from the pure solid
