A solution of H 2 SO 4 ( aq ) H2SO4(aq) with a molal concentration of 4.80 m 4.80 m has a density of 1.249 g / mL . 1.249 g/mL. What is the molar concentration of this solution?

The answer to your question is Molarity = 4

Explanation:

Data

molalidad = 4.8

density = 1.249 g/ml

molarity = ?

Process

1.- Calculate the moles of H₂SO₄

   molality = moles / kilogram

Solve for moles

   moles = molality x kilogram

Substitution

   moles = 4.8 x 1

Result

   moles = 4.8 moles

2.- Calculate the mass

- Mass of solute

 Molar mass of H₂SO₄ = 2 + 32 + 64

                                      = 98 g

          98 g 1 mol

            x     4.8 moles

           x = (4.8 x 98)/1

           x = 470.4 g

Total mass = 470.4 + 1000

                  = 1470.4 g

3.- Calculate the volume

Density = mass/volume

Volume = mass/density

Substitution

Volume = 1470.4/1.249

             = 1177.3 ml

4.- Calculate molarity

Molarity = moles / volume (L)

Molarity = 4.8 / 1.177

Molarity = 4.0      

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

the answer is definitely c.
