Answer: B) Pure water

Explanation: Electrolytes are those solutions which consists of ions and thus can easily conduct electricity through them.

a) Ocean water contains dissolved minerals which act as electrolytes and hence act as a good electrolyte.

b) Pure water is present in undissociated form due to strong hydrogen bonding and thus due to the absence of ions, act as a non electrolyte.

c) Strong hydrochloric acid: is a strong acid which easily dissociates to give H^+ ions and thus act as good electrolyte.

HCl\rightarrow H^++Cl^-

d) Potassium chloride is a salt which act as good electrolyte due to easy dissociation of ions in water.

KCl\rightarrow K^++Cl^-

A sample of gas (1.9 mol) is in a flask at 21 °C and 697 mm Hg. The flask is opened and more gas is added to the flask. The new
Artyom0805 [142]

Answer: There are now 2.07 moles of gas in the flask.

Explanation:

PV=nRT

P= Pressure of the gas = 697 mmHg = 0.92 atm  (760 mmHg= 1 atm)

V= Volume of gas = volume of container = ?

n = number of moles = 1.9

T = Temperature of the gas = 21°C=(21+273)K= 294 K   (0°C = 273 K)

R= Value of gas constant = 0.0821 Latm\K mol

V=\frac{nRT}{P}=\frac{1.9\times 0.0821 \times 294}{0.92}=49.8L

When more gas is added to the flask. The new pressure is 775 mm Hg and the temperature is now 26 °C, but the volume remains same.Thus again using ideal gas equation to find number of moles.

PV=nRT

P= Pressure of the gas = 775 mmHg = 1.02 atm  (760 mmHg= 1 atm)

V= Volume of gas = volume of container = 49.8 L

n = number of moles = ?

T = Temperature of the gas = 26°C=(26+273)K= 299 K   (0°C = 273 K)

R= Value of gas constant = 0.0821 Latm\K mol

n=\frac{PV}{RT}=\frac{1.02\times 49.8}{0.0821\times 299}=2.07moles

Thus the now the container contains 2.07 moles.
