What is the molarity of a solution made by dissolving 100.00 grams of sodium chromate in 5.00 liters of solution?

First of all we need no.of moles of 100g sodium chromate

Molar mass of sodium chromate = 161.97g/mol

No of mole =mass in gram/molar

=100/161.97

= 0.617mol

Now to find molarity apply formula

Molarity= moles of solvent/solution in liter

= 0.617/5

=0.1234M solution of sodium chromate

your answer would be “dry”
