Question

a student in lab needs to make a solution that is 6.00 % by mass nacl. if 175 g of nacl is available, what mass of solution can be prepared?

Answer 1

The mass of 6.00% by mass NaCl solution that can be prepared from 175 g of NaCl is 2916.67 g

Calculating the mass of a solution that can be prepared

From the question, we are to determine the mass of the solution that can be prepared

From the given information,

The student in lab needs to make a solution that is 6.00% by mass NaCl

and

175 g of NaCl is available

Let the mass of solution that can be prepared be x.

Then, we can write that

6.00% of x = 175

6/100 × x = 175

0.06 × x = 175

Divide both sides by 0.06

x = 175 / 0.06

x = 2916.67 g

Hence, the mass is 2916.67 g
