a) Given a measured aqueous oxygen ($O_2$) concentration of 10 mg/l, what is the corresponding molar concentration? b) What is the concentration in mg/L of a 0.005 M solution of $H_2SO_4$? c) What is the total mass of $Mg(OH)_2$ in 4 liters of a 0.20M solution?

Step 1
To do this, we need to know the molar mass of oxygen (O2). The molar mass of O2 is 32 g/mol. First, convert the mass concentration from mg/L to g/L: 10 mg/L = 10/1000 g/L = 0.01 g/L Show more…
