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
Answer:I believe your answer would be option B) dilute. Hope this helps.
Explanation:
It's -Bohr's Model- becuase Dalton I dont think did a model. Thomson's was the "Plum Pudding Model." Ernest Rutherford drew one out(I dont know i dont have a model down though) so it the only one left is Dalton's Model which is it. (Hopefuly)
