When in aqueous solution, K2CrO4 dissociates into ions. It dissociates into:
K2CrO4 = 2K+1 + CrO4-1
We do as follows:
Molarity = mol / L = 0.38 g/g solution ( 1.37 g/mL ) ( 1 mol / 194.19 g ) ( 1 mol CrO4-1 / 1 mol K2CrO4 ) ( 1000 mL / 1 L ) = 2.68 M
X = larger number
x-1 = smaller number
x*(x-1)=5+3x
x^2-4x-5=0 use the formula
x=5
x-1=4
the 2 numbers are 5&4 or -1,-2
