The molar concentration of 250ml solution that contain5g Na2CO3 is?

Molarity = 0.2 M

Explanation:

Given data:

Molar concentration = ?

Volume of solution = 250 mL (250 mL/1000 = 0.25 L)

Mass of Na₂CO₃ = 5 g

Solution:

Number of moles of Na₂CO₃:

Number of moles = mass/molar mass

Number of moles = 5 g / 106 g/mol

Number of moles = 0.05 mol

Molarity = number of moles / volume of solution in L

Molarity = 0.05 mol / 0.25 L

Molarity = 0.2 M (M = mol/L)

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.
