200 g of \(20 \% \mathrm{w} / \mathrm{w}\) urea solution is mixed with 400 g of \(40 \% \mathrm{w} / \mathrm{w}\) urea solution. What is the weight percentage (w/w \%) of resultant solution?
- A 30.33
- B 33.33
- C 36.33
- D 28.33
Answer & Solution
Correct Answer
(B) 33.33
Step-by-step Solution
Detailed explanation
200 g of \(20 \%\) urea contain 40 g urea in 200 g solution 400 g of \(40 \%\) urea contain 160 g urea in 400 g solution. Total amount of solution \(=600 \mathrm{~g}\) Total amount of urea in solution \(=200 \mathrm{~g}\) Hence, Weight \(\%\) of urea in solution…
