Find the molarity of a 450 mL solution containing 13.7 g of ZnSO4.

The molarity is 0.189

Explanation:

Molarity is a measure of concentration of a solution that indicates the number of moles of solute that are dissolved in a given volume. In other words, the molarity indicates the amount of moles of solute that appear dissolved in each liter of the mixture.

Molarity is determined by the expression:

Molarity is expressed in units ().

So, you need to know the amount of moles of ZnSO₄. Then you must know the molar mass. If:

the molar mass of ZnSO₄ is:

ZnSO₄= 65 g/mol + 32 g/mol + 4* 16 g/mol= 161 g/mol

Then you can apply a rule of three as follows: if 161 g of ZnSO₄ is contained in 1 mole, 13.7 g in how many moles are they?

moles=0.085

Then you know:

Replacing in the definition of molarity:

Molarity=0.189

The molarity is 0.189

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.
