ANSWER ASAP PLEASSE
A silver nitrate solution contains 16.75 g of primary standard AgNO3 in 1.00 L. What volume of this solution will be needed to react with 25.00 mL of 0.0545 M Na3PO4?
Problem 3. A cell contains K+, Cl¯and an impermeant anion A™. It is bathed in a
solution of K+ and Cl-. T= 300K. The cell's membrane is permeable to Cl- only. If CA¹ =
110 mM and cClº = 150 mM, find the values of CK¹, ckº, cci', and Vm such that the system
is in osmotic equilibrium and both sides are electroneutral (i.e., positive and negative
charges cancel each other out within both the inside and outside solutions).
