AVprozaik [17]

For the answer to the question above, use these formulas in solving your problem and as a guide.

MM = 342 (g/mol) 

171 (g) / 342(g/mol) = x mol of sucrose 
x moles of sucrose/ 1.25 L = Molarity of soultion

I hope I helped you with your problem. Have a beautiful day!

a 10.99g sample of NaBr contains 22.34% Na by mass. Considering the law of constant composition (define proportions), how many g

leonid [27]

Given :

A 10.99 g sample of NaBr contains 22.34% Na by mass.

To Find :

How many grams of sodium does a 9.77g sample of sodium bromine contain.

Solution :

By law of constant composition , in any given chemical compound, the elements always combine in the same proportion with each other.

Therefore , percentage of Na by mass in NaBr will be same for every amount .

Percentage of Na in 9.77 g NaBr is 22.34 % too .

Gram of Na = $9.77\times \dfrac{22.34}{100}=2.18\ g$ .

Hence , this is the required solution .
