The pressure of 1.5 mole sample of radon gas with a volume of 21.0 L at 33° C should be determined. Concept Introduction: The pressure of radon gas in this case can be determined using ideal gas law . Ideal gas law is a hypothetical law and mathematically expressed as: PV = nRT Where, P is the pressure of gas V is the volume of the gas T is the absolute temperature of the gas R is the gas constant and n is the number of moles of the gas molecules.

Answer 1

Question

Chapter 13.5, Problem 13.6SC

Interpretation Introduction

Interpretation:

The pressure of 1.5 mole sample of radon gas with a volume of 21.0 L at 33° C should be determined.

Concept Introduction:

The pressure of radon gas in this case can be determined using ideal gas law. Ideal gas law is a hypothetical law and mathematically expressed as:

PV = nRT

Where,

P is the pressure of gas

V is the volume of the gas

T is the absolute temperature of the gas

R is the gas constant and

n is the number of moles of the gas molecules.

Calculating the pH at equivalence of a titration Try Again Your answer is incorrect. 0/5 a A chemist titrates 70.0 mL of a 0.7089 M hydrocyanic acid (HCN) solution with 0.4574M KOH solution at 25 °C. Calculate the pH at equivalence. The pK of hydrocyanic acid is 9.21. Round your answer to 2 decimal places. Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of KOH solution added. pH = 11.43] G 00. 18 Ar B•
