i am taking biology chemistry german and music. all of my subjects i am doing so well in except chemistry. i used to want to do medicine but now i have changed my mind and either want to do german at uni, music at unit, or a combined course of both. i really want to drop chemistry as I am trying so hard but cannot get even satisfactory grades. it depresses me. however i feel like my mum and dad are pressurising me into doing a scientific career. mum says i should keep it on for the first year and see what my results are but i feel as if i am wasting my time when i could be concentrating more on the subjects i enjoy. its so depressing help me!someone! thanks! xx

An aqueous solution of NaNO3 has a concentration of 0.363 molality. Its density is 1.0185 g mL ^ -1. Calculate the molar concentration of NaNO3 and the mass percent of NaNO3 in the solution. What is the mole fraction of NaNO3 in the solution?

answers should be
0.359 Molarity
3.00% mass (percent NaNO3)
6.49 x 10 ^ -3 (mole fraction)

Can anyone please explain how to do the problem? I appreciate any help thank you

My first guess was that it was catabolic due to the fact that it takes glucose and breaks it down to pyruvate while releasing energy in ATP. It also is oxidative in the sense that NADH is generated. Though on the internet I read it was an anabolic pathway. Can someone please explain or give a good link.
