It takes 12.5 mL of a 0.30 M HCl solution to neutralize 285 mL of NaOH solution.
liq [111]

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

daser333 [38]

Answer:

You make $270 every two weeks. Since you pay rent on the first of every month you will have made two paychecks which would equal out to $540.00 a month.. apartments usually run $700 or more a month... So sorry man, you cant afford an apartment. however, you might be able to find one that cheap, but its very very very rare. You will also not be able to afford food or any bills that will come your way..
