1) The longer the quarrying goes on the less and less recources we will have, soon leading to no more recources
24.5 / 14 = 1.75
70 / 16 = 4.375
4.375 / 1.75 = 2.5
empirical formula = N2O5
Answer:
0,20M of nitric acid
0,00250M of KSCN
Explanation:
For nitric acid, the dilution is from 10,00mL to 100,00mL. That is a 1/10 dilution. As the initial concentration of nitric acid is 2,0M, the new concentration is: <em>2,0M× (1/10) = </em><em>0,20M of nitric acid</em>
<em></em>
For KSCN the dilution is from 50,00mL to 100,00mL, that is a dilution 1/2. Thus, the new concentration of KSCN is:
<em>0,00500M × (1/2) = </em><em>0,00250M of KSCN</em>

I hope it helps!
