Molecular mass of compound is sum of atomic mass of each atoms constituted in the compound. Equation for density is, Density = Mass Volume According to ideal gas equation, Pressure × Volume = Mass × R × Temperature Molecular mass Ideal gas equation in terms of Density, Density = Pressure × Molecular mass R × Temperature

Question

need help not sure what am doing wrong step by step please answer is 971A During the lecture, we calculated the Debye length at physiological salt concentrations and temperature, i.e. at an ionic strength of 150 mM (i.e. 0.150 mol/l) and a temperature of T=310 K. We predicted that electrostatic interactions are effectively screened beyond distances of 8.1 Å in solutions with a physiological salt concentration. What is the Debye length in a sample of distilled water with an ionic strength of 10.0 µM (i.e. 1.00 * 10-5 mol/l)? Assume room temperature, i.e. T= 298 K, and provide your answer as a numerical expression with 3 significant figures in Å (1 Å = 10-10 m).

Chapter 5, Problem 79E

Interpretation Introduction

Interpretation: The density of uranium hexafluoride is to be calculated at 60∘C and 745 torr. (The boiling point of UF6 is 56∘C )

Concept introduction:

Boiling point is the temperature at which the liquid compound will boil and transform to gaseous state.

Molecular mass of compound is sum of atomic mass of each atoms constituted in the compound.

Equation for density is,

Density = MassVolume

According to ideal gas equation,

Pressure × Volume = Mass × R × Temperature Molecular mass

Ideal gas equation in terms of Density,

Density = Pressure × Molecular mass R × Temperature
