What is the molarity of a solution that is 26.0% by mass in phosphoric acid, H3PO4, and that has a density of 1.155 g/mL?
steposvetlana [31]

Answer: The molarity of a solution that is 26.0% by mass in phosphoric acid is 3.06 M

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

Molarity=\frac{n\times 1000}{V_s}

n = moles of solute

V_s =volume of solution in ml

Given : 26.0 g of phosphoric acid in 100 g of solution.

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}=\frac{26.0g}{98g/mol}=0.265moles

Volume of solution =\frac{\text {Mass of solution}}{\text {Density of solution}}=\frac{100g}{1.155g/ml}=86.6ml

Molarity=\frac{0.265\times 1000}{86.6ml}=3.06M

Molarity of a solution that is 26.0% by mass in phosphoric acid is 3.06 M

___________ would albumin expect to dissociate into individual ions and increase the number of osmols/mol in solution.
Lubov Fominskaja [6]

Answer: Check explanation please.

Explanation:

Before diving into the question,let us consider some important facts and definitions.

WHAT IS OSMOLARITY? Osmolarity is the number of OSMOLES of solute per litre of the solution. The unit of osmolary is OSMOLE. Nowadays, osmolarity has become a term used in the past, now osmolarity is called osmotic concentration.

OSMOLARITY can be calculated using; Σ(osmotic coefficient × number of ion × the solute molar concentration).

BACK TO THE QUESTION; ALBUMIN is a PROTEIN. Protein is a large molecule and it contributes an insignificant amount to osmolarity(around 0.6 Mosmole/litre).

Also, if we have the osmotic coefficient to be between zero and one, there is going to be great DISSOCIATION.
