Step-by-step explanation:
= (4)(102)
= 408 (408) (0.04) = 16.32 16.32/7.2
= 2.26666667
5 liters (L) of 30% bleach solution contains 0.3×(5 L) = 1.5 L of bleach.
3 L of 50% bleach contains 0.5×(3 L) = 1.5 L of bleach, too.
Combined, you would have 8 L of solution containing 1.5 L + 1.5 L = 3 L of bleach, so the concentration of bleach is
(3 L) / (8 L) = 0.375 = 37.5%
It is not.
400 decimeters = 4,000 cm
4,000 cm = 40 m
