Question Volume of gasses produced in electrolysis

After electrolysis of sodium nitrate aqueous solution the mass fraction of sodium nitrate was 60%. The mass fraction of sodium nitrate before electrolysis was 40%. What is the overall volume of gasses produced during the electrolysis at temperature of 20C and pressure of 99.8 kPa?

I don't know how to start. I'm lost. Everything would be fine if I had masses but I don't know what should I do with just fractions.
