Long-term trends in phytoplankton composition in the western and More than 75 percent decline over 27 years in total flying insect biomass in protected areas

N: 19%. O: 65%. 8) (NH4)3PO4. N: 28%. H: 8% H = 1.00794g. Now find the molecular mass of HCl: 1.00794g + 35.4527g = 36.46064g. Follow steps 3 and 4: (1.00794g/36.46064g) x 100 = 2.76% Now just subtract to find the percent by mass of Chlorine in the compound: 100%-2.76% = 97.24% Therefore, HCl is 2.76% Hydrogen and 97.24% Chlorine by mass.
