1. Calculate the molarity of .40 more of NaCl dissolved in 1.6 L of solution

2. Calculate the molarity of 20.2 g of potassium nitrate in enough water to make tone 250.0 mL of solution

3. Regulate the number of grams needed to make 2.0 L of 2.0 M nitric acid solution

4. What is the molarity of a solution that contains 212.5 I was of sodium nitrate in 3.0 L of solution

Please please help I can’t do this

Answer is to avoid experimental error

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na

Hi; /c

The answer is accuracy
