Hi everyone. Could anyone answer this simple question... If i had 6.58ml of 36% HCl and i wanted an equimolar quantity of K2CO3, How many  grams of K2CO3 would i need ? Please show how you get the answer. Thank you

You will need density of HCl solution.

What data do you need to calculate number of moles of HCl?

I'm trying to get my head around calculating the density and moles etc... i'm new to this, and trying an experiment at home and i'm stuck

  HCl Molar mass 36.46 g/mol (HCl) is this based on a litre ? Density 1.18 g/cm3  is this based on 100% HCl please help
