Question

sodium salt of an acid dye contains 7% sodium
what is minimum molor mass of dye​

Answer 1

Answer:

Explanation:

Hey there,

We know Molar mass of Sodium = 23g/mol, and we are given that the percentage of sodium (Na) in methyl orange molecule = 7.

So, let the Sodium salt of methyl orange be x

Therefore, X ×7100=23x×7100= 23

x= 23×1007x= 23×1007

x= 328.57x= 328.57

Molecular weight is calculated as per the relative atomic mass of each constituent elements, and in the given problem it is 328.57.  

I hope it was helpful.
