I need some help making a 15N solution. Please tell me how much gram of NH4NO3 to be need to make 10% NH4NO3 1L or 100ml solution. NH4NO3 usually contains 33% nitrogen, its molar mass is 80.052 g/mol and chemical purity is 99%.

Many thanks,

Do you know what the N means here?

Start with the definition - what does it mean 10% solution?
