help with molarity

[channing2]

can someone please help me work this problem? sulfuric acid solution contains 571.6 grams of water per liter of solution and has a density of 1.329 g/cm(cubed). what is the molarity?

[Cap'n Refsmmat]

There are 1000cm³ in one liter, so the density (in an easy form) is 1329g/L. In one liter, 571.6 grams are water, and the remainder is sulfuric acid. Figure out how many moles are in that remainder and divide by the number of liters you have (one) and you have molarity.

a very simple equation would be:

 

molarity=moles of solute\liter of solution

 

BTW, check this!

Molarity is the term used to describe the concentration of a solution. In other words, it is the number of moles of solute dissolved in 1 litre of solution.

A mole is a unit of measurement for a chemical substance. Molarity emerged from mole, coined by German chemist from Molekul which means molecule.

Molarity (M) = Moles of solute/Litres of solution

Where, solute is the substance dissolved, solvent is the substance where the solute is dissolved (usually water) and the solution is the combination of both solute and solvent.

Molarity Equation examples:

Example 1. Find the Molarity of a solution where 1.56 moles of sugar is dissolved in 2.79 L of solution?

Answer: Molarity (M) = Moles of solute / Litres of solution
Molarity (M) = 1.56 moles of sugar / 2.79 L of solution
= 0.559 moles/L

13.5 M ?

[hypervalent_iodine]

13.5 M ?

Nope.

Although, I am pretty sure the OP has the question wrong. I suspect that it should say that the solution contains 571.6 g/L of sulfuric acid, not water.

@OP, Please show your work in opening post in the future.
