Answer: Volume of 0.25 M solution is 38 ml

Explanation:   Amount of substance n remains same.

 n = c1V1 = c2V2    Solve V2 = V1c1 / c2 = 73,0 ml · 0.13 M / 0.25 M = 37.96 ml

Answer:

3.6g

Explanation:

2 moles of water gives 1 mole of oxygen

2(h2o)=1(o2)

2(molar mass of h2o)=1(molar mass of oxygen molecule)

2(18)=1(16×2)

36=32

3.6=x

cross multiply

3.6×32=36× x

115.2=36x
