Stoichiometry A very dilute solution is prepared by dissolving 'x1' mole of solute in 'x2' mole of a solvent. The mole fraction of solute is approximately equal to 1/x2 X1/x2 1 - (x1/x2) X2/x1 1/x2 X1/x2 1 - (x1/x2) X2/x1 ANSWER DOWNLOAD EXAMIANS APP

Stoichiometry Sometimes, in chemical processes, a part of the outlet stream is rejected as waste in order to keep the impurity level in the system within limits. This phenomenon is termed as the Recycling Purging Recirculation Bypassing Recycling Purging Recirculation Bypassing ANSWER DOWNLOAD EXAMIANS APP
