Calculate the strength of 10 volume Solution
of hydrogen peroxide

10 volume solution of H2O2 means that 1L of this H2O2 solution will give 10L of oxygen at STP. Hence, strength of H2O2 in 10 volume H2O2 solution = 30 g / L = 3% H2O2 solution.

step-by-step explanation:

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
