    I find this question quite difficult. Can anyone explain how to do this?

    A sample of concentrated sulphuric acid has a density of 1.83gcm^-3 and contains 94% of sulphuric acid by mass. What is the concentration of sulphuric acid in the sample?

    assume you have a liter, it then weights 1,83kg, or 1830g. 94% of its is sulpharic acid. wich is 1720,2g. molarmass of sulphuric acid is 98,08. divide 1720,2g with 98,08g/mol and you get the moles wich is 17,53mol, divide with volume, wich is 1 liter, and you get a C of 17,53Molar
