What is the molar concentration of an aqueous solution that has 200g of Iron (II) Chloride dissolved in 450mL of water? (convert to moles then solve for Molarity)

We are given:

200 grams of FeCl₂ in 450 mL of water

Number of Moles of FeCl₂ in 450 mL:

Molar mass of FeCl₂ = 127 grams/mol (approx)

Number of moles = Given mass / molar mass

replacing the variables

Number of moles = 200 / 127

Number of moles = 1.57 moles

Number of Moles of FeCl₂ in 1 L (Molarity):

We know that in 450 mL of the solution, we have 1.57 moles

Molarity of the solution = Number of moles / Volume of solution (in L)

Molarity of the solution = 1.57 / 0.45

Molarity of the solution = 3.489 M

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.
