2007 past paper #27(a)
If the volume of the water sample being tested is 50mL and the mass of the dired ppt obtained is 3.65 g, calculate the chlorine ion concentration in the water sample in ppm.
Is this right?
3.65g/50.0 mL=3.65g/(0.05L)=73g/L
73g/L X1000= 73000mg/L=73000ppm
1ppm=1mg/L=1g/L x1000
PLEASE HELP ME! Thanks!
