4) A student wishes to check the amount of HCI found in a bottle in lab. On the label of the bottle, the concentration of HCI is expressed as mg per liter of solution. Help her determine how much of her NaOH solution will be required to titrate 50.00 mL of the solution in the assigned option below. A HCl + NAOH → Nac + Hz ОРТION How many mL of Ob27 ?M NAOH will be required to titrate 50.00 mL of the HCI labeled y51 mg HCI/L? Hint: a) Change mg/L to mole/L of HCI b) Find moles of HCI c) Convert to moles of NaOH d) Find mL of NaOH
