Question

hi
In Question 2 above, if 1 part of a red pigment requires 75 mL of base, how much red pigment should we mix with 1800 mL of base?

Answer 1

Parts of base (in mL)

The parts of red pigment and the parts of base are in direct proportion. Thus, 24 parts of red pigments should be mixed with 1800 mL of base.

hope this helps you
