Question #172368

What is the molar concentration of a 2% by mass H2SO4 solution with density of 1.24gmL?

Expert's answer

The density of 2% H2SO4 is 1.24 g/mL

This tells us that a liter of % H2SO4 would have a mass of 1240 gms,

2% of 1240 is 24.8 g H2SO4

24.8 g H2SO4 /98 = 0.2531 moles/L

Therefore, the molarity of 2% H2SO4 is 0.2531 M
