hey po..pahelp po..pki sagot yung examples! need ko na po now...pasagot po ng maayos, accurate at matino please.

how to calculate the formula of:
% by volume
% by mass

formula:
\frac{volume \: of \: solute}{volume \: of \: solution \: \times 100\% \: }
volumeofsolution×100%
volumeofsolute
​


\frac{mass \: ofsolute}{mass \: ofsolute + mass \: of \: solvent \: \times 100\%}
massofsolute+massofsolvent×100%
massofsolute
​

calculate the examples:

% by mass:
\frac{255}{36.5} \times 100\%
36.5
255
​
×100%
% by volume:
\frac{90}{3000 \times 100\%?}
3000×100%?
90
