How much ch2o is needed to prepare 445 ml of a 2.65 m solution of ch2o?

35.4 grams

Explanation:

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

where,

Molality = 2.65

n= moles of solute =?

  = volume of solution in ml = 445 ml

Putting in the values we get:

Mass of solute in g=

Thus 35.4 grams of is needed to prepare 445 ml of a 2.65 m solution of .

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
