solutia1
ms1=200x1,496 g=299,2g
c=mdx100/ms----> md1=c1xms1/100=92x299,2/100g=275,26gHNO3
solutia2
ms2= 200x1,841g=368,2g
md2= c2xms2/100= 98x368,2/100g=360,84gH2SO4
solutia finala, contine atat HNO3 cat si H2SO4
msf= ms1+ms2=667,4g
md,HNO3= 275,26g
c,HNO3= 275,2x100/667,4=>41,24%HNO3
md,H2SO4= 360,84g
C,H2SO4=360,84x100/667,4=54,07%H2SO4
