Question

How many grams of table salt are present in 240g salt solution containing 3.5%table salt

Answer 1

Answer:

8.4 grams of table salt are present in 240g salt solution containing 3.5%table salt.

Explanation:

First, let's calculate mass by the mass percentage of the solution. Which is given as,

$\mathrm{\%=\frac{w}{W}\times 100 }$             (1)

Where,

w=given mass of the table salt

W=Total mass of the solution

From the question we have,

The total mass of the solution (W)=240 grams

The mass percentage of the solution=3.5%

When we enter the values into equation (1), we obtain;

$\mathrm{3.5=\frac{w}{240}\times 100 }$

$\mathrm{\frac{w}{240}=0.035 }$

$\mathrm{w=8.4\ grams}$

So, 8.4 grams of table salt are present in 240g salt solution containing 3.5%table salt.

Answer 2

Answer:

The grams of table salt are present in 240g salt solution containing 3.5%table salt is 8.4 grams .

Explanation:

Concept: Mass by mass percentage

% w/ W × 100

w-given mass of the table salt

W-Total mass of the solution

Given:

w= ?

W= 240g

%=3.5 %

Step by step explanation

From the question we have,

The solution's entire mass (W) is 240 grammes.

The solution's mass percentage is 3.5 yields the following results when we insert the values:

3.5 =w/ 240 × 100

w/ 240 = 0.035

w= 8.4 grams

Hence , the grams of table salt are present in 240g salt solution containing 3.5%table salt is 8.4 grams .
