The results of a titration experiment we as follows:

Volume pf aqueous NaOH pipetted into conical flask = 10mL.

Molarity of dilute HCl = 1.196 M

(i) write the chemical reaction equation for the titration reaction.

(ii) calculate the number of moles of HCl added during titration

A sample of cisplatin is 65.02% platinum, 9.34% nitrogen, 2.02% hydrogen, and 23.63% chlorine. Determine the empirical formula.


7. If you get a chance to read the instructions on a bottle of deodorant, you might have read the warning signs indicating the bottle to be kept away from the sunlight and high temperature. Ever wondered why?


4. If you have had the chance to go out on a chilly day, you might have noticed that the balloon crumbles. However, if you take the balloon to a warm room, it regains its shape. Why does this happen?



Solve: What is the volume of a container that can hold 0.50 mole of gas at 25.0°C and 1.25atm?

Given: V1 = ?

n = 0.50 mole

T = 250C + 273.15= 298.15 K

P = 1.25 atm

R = 0.0821 L atm/ mol K


Solve: What will be the final volume of a 5.00 L He gas which contains 0.965 mole at 30°C and 1.00 atmosphere, if the amount of this gas is increased to 1.80 moles provided that the temperature and pressure remains unchanged?

Given: V1 = 5.00L                                                       V2 = ?

T𝟏 = 0.965 mole                                            T𝟐 = 1.80 moles



Solve: A certain light bulb containing argon has a pressure of 1.20 atm at 18°C. If it

will be heated to 85°C at constant volume, what will be the resulting pressure? Given: P1 = 1.20 atm.                                                                             P2 = ?

T1 = 180C + 273.15= 291.15 K                            T2 = 850C + 273.15=358.15 K

 


Solve: Helium gas has a volume of 250 mL at 0°C at 1.0 atm. What will be the final

pressure if the volume is reduced to 100 mL at 45°C?

Given: V1 = 250mL                                                       V2 = 100 mL

T1 = 00C + 273.15= 273.15 K                     T2 = 450C + 273.15=318.15 K P1 = 1 atm                                                                    P2 = ?
