Hello could you help me answer to one question please.

From 98% Sulphuric acid to make 50ml 5% sulphuric acid How to DIlute
with water , how much need ?


Answered by DrBob222
mL1 x %1 = mL2 x %2
mL1 x 98% = 50 mL x 5%
Solve for mL 1.
Add that amount to 50 mL volumetric flask and make to the mark with distilled H2O.
