Answer:
0.013 M NaOH
Step-by-step explanation:
HCL + NaOH = NaCL + water
The mole ratio of acid and base is 1:1
Molarity is equal to the moles of solute divided by the liters of solution
Solute mole = 12.5 × 10^-3 × 0.3
= 0.003075
To neutralize 0.00375mol of HCl, 0.00375 mol of NaOH will be required. Since molarity is moles per liter, divide this amount of moles by the volume in liters:
Molarity = 0.00375/285 × 10^-3
Molarity = 0.0131 M
Answer:
The answer would be 8 but I'm not that great at math try at your own risk
Okay uhm.. guessing, guessing..-
1 = D
2 = E
3 = A
4 = B
5 = F
6 = C
If these are not right, sorry. :<
Hope this helps?
