this is killing me.
the question ask for total charge ina given volume of water.
-first convert the volume to m^3 from cm^3 since i know the density of water at 4 degree cel (most dense) is 1000kg/m^3.
-then imultiply the m^3 by 1000kg/m^3. then convert it to grams.
- divide by 18 grams (mass of H2O). which will gives us # of moloe of H2O. then multiply by 6.02*10^23 to get the amount of molec of H2O.
-Multiply by 10 electron (since each H2O have 10 e total).
-then lastly multiply it by 1.6*10^-19 C (charge of an electron)
but still i keep gettign the wrong answer. anyone know why?
