Given the equilibrium reaction  MgF2(s) ↔ Mg+2(aq) + 2F-(aq)                      Ksp = 7.4x10-11 Calculate the amount of MgF2(s)  in grams needed to create One Liter of a saturated solution in standard conditions?

You are asked to weigh 2 g of  lithium and add it to 1500 ml of distilled water +2 drops of indicator, knowing that the density of water is 1 at room temperature while conducting this experiment. After determining the molarity of the LIOH, you need to know how many volume should be taken to reach the final concentration. Therefore, use the one underneath, so the molarity after dilution will be 0.025 M instead  of 0.25 MAfter knowing the amount of LiOH, you need to dilute to prepare 0.025 M of LiOH in a 3000 ml solution. Show your calculation  and units.

What is the activity coefficient for each ion at the given ionic strength at 25 °C? Activity coefficients at various ionic strengths can be found in this table. SO (μ= 0.1 M) y = Y³+ (μ = 0.01 M) y = Pr³3 + (μ = 0.1 M) Y = (CH₂CH₂)₂NH+ (μ = 0.05 M) y = 0.8 x10 TOOLS
