Answer: 2.04 moles
Explanation:
Mass of H2SO4 = 200g
RMM of H2SO4 = (2*1) + 32 + (16*4)
= 2 +32 +64 = 98
n = Mass concentration / RMM
n = 200/98
n = 2.04moles
Cr(NO3)3
because Chromium (III) formula is Cr2O3 And Nitrate formula is NO3
This type of mixture is a heterogeneous mixture. It is any mixture that is not uniform. Heterogeneous mixtures always have more than one phase.It is made up of substances which stays physically separate with each other. Best example is a mixture of sand and sugar. If you get two samples from different points of the mixture and analyze it, you will see that the concentrations of the components are different and that the two solid phases never combine with each other.
