Concentration of the reactant,pressure,surface
area of the reactant and temperatur
The symbol %v/v means percent by volume. Assuming there is no volume effects when these substances are mixed, we calculate as follows:
% v/v = (25 mL ethanol / 25 mL + 150 mL ) x 100
%v/v = 14.29 mL ethanol / mL solution
Hope this answers the question.
I think c may be your anwser but im not too sure :/ srry if u get it wrong!
