Vapour density=Mass of certain of gas(22.4L)at STPMass of same volume ofH2gas(22.4L)at STP =Mw2 i.e., Molecular mass of gas=Vapour density ×2 Vapour density is a unitless quantity it is unaffected by variation of temperature and pressure. The vapour density of a mixture containi...
How are percent transmittance and absorbance related algebraically? Under what conditions can an enzyme assay be used to determine the relative amounts of an enzyme present? What is the advantage of reading the absorbance rather than the percent transmittance on ...
Fig. 6. A summary of the Risk Quotient (RQ)s of target metals and metalloid and the corresponding Integrated Risk Quotient (IRQ) value (both unitless). On a different note, the presence of calcium in competition with lead can influence (1) the absorption of lead in the intestines, (2)...
