Answer 1

Question

Chapter 11, Problem 15PS

Interpretation Introduction

Interpretation: The approximate gas pressure of ether at 30o C should be determined. The additional ether is whether evaporated or condensed when placed in an ice bath should be determined

Concept Introduction: Vapor pressure is nothing but the pressure of a vapor in contact with its liquid or solid form.

When a liquid and vapor are in equilibrium the pressure exerted by the vapor is called the equilibrium vapor pressure.

The ideal gas equation is,

PV = nRTwhere, P = Pressure V = Volume n = Number of moles R = Gas constant T = Temperature

From its given mass is,

Number of moles = Given massMolecular mass

There is an instrument in Johnson 334 that measures total-reflectance x-ray fluorescence (TXRF) to do elemental analysis (i.e., determine what elements are present in a sample). A researcher is preparing a to measure calcium content in a series of well water samples by TXRF with an internal standard of vanadium (atomic symbol: V). She has prepared a series of standard solutions to ensure a linear instrument response over the expected Ca concentration range of 40-80 ppm. The concentrations of Ca and V (ppm) and the instrument response (peak area, arbitrary units) are shown below. Also included is a sample spectrum. Equation 1 describes the response factor, K, relating the analyte signal (SA) and the standard signal (SIS) to their respective concentrations (CA and CIS).
