3) The inside volume of a motorhome is 800m3. Assume T=20.2C, the gauge pressure inside the home is - 19.1 Pa. What mass of formaldehyde (HCHO, MW= 30g/mol ) vapor is inside the home if the measured indoor air concentration of formaldehyde is 0.7ppbv ? 4) Consider the following water analysis reported for a sample of contaminated groundwater obtained near the effluent of a manufacturing facility: pH=11.2,Na+=6,500mg/L,Cl=1,100mg/L2,CO32= 1,740mg/L (as C), Ca2+=3,400mg/L,K+=2,230mg/L,F=4,350mg/LSO42=3,940mg/L2,Mg2+= 1,350mg/L a) Does the charge balance for this analysis meet the Charge Balance Error
