Calculate the hydrogen ion concentration [H^+]/[H3O^+] of an aqueous solution given the concentration of hydroxide ions [OH^-] is 1 x 10^-5 M (hint: find the pOH then the pH and then the [H^+]

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

so what is the problem with your lab report and whats the subject of the lab report? i will you

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
