Question

4g of potassium chloride is dissolved in 6g of water. The concentration of the solution is
A. 4%
B. 0.4%
C. 40%
D. None of the above​

Answer 1

Answer:

C) 40%

please mark it brainliest answer

Explanation:

mass of KCl. =4g

mass of H2O=6g

total =10

%=4/10*100

=40%

Answer 2

Given: 4g of potassium chloride is dissolved in 6g of water.

To find: We have to find out the concentration of the solution.

Solution:

4g of potassium chloride is dissolved in 6g of water.

So total mass is (4+6=10g).

The amount of potassium chloride in water is 4 grm.

The concentration of the solution is a ratio of 4 to 10 multiple by 100.

$\frac{4}{10} \times 100\% \\ = 40\%$

The concentration of the solution is 40%.

The concentration of the solution is 40%.So, correct option is C.
