Question

a solution contains 16 gram of NaCl in 304 gram of water calculate concentration
​

Answer 1

Explanation:

Given

A solution contains 16 gram of NaCl in 304 gram of water

To Find

Concentration

We know that

\sf \longrightarrow \% \ Concentration=\dfrac{Mass \ of \ Solute}{Mass \ of \ Solution} \times 100⟶% Concentration=

Mass of Solution

Mass of Solute

×100

Given that

A solution contains 16 gram of NaCl in 304 gram of water

Here

Solute = NaCl

Solvent = Water

Hence

Mass of Solute = 16 g

Mass of Solution = 16 + 304 = 320 g

Substituting the values

We get

\sf \longrightarrow \% \ Concentration=\dfrac{16}{320} \times 100⟶% Concentration=

320

16

×100

\sf \longrightarrow \% \ Concentration=0.05 \times 100⟶% Concentration=0.05×100

Hence

\sf \longrightarrow \% \ Concentration= 5⟶% Concentration=5

Therefore

Concentration = 5 %
