[chawki]

Homework Statement

Calculate the concentration of water and table salt, when 250 grams of table salt NaCl is in 3
litres of liquid. Table salt has a molecular mass of 58,5 g/mol.

Homework Equations

Give the answer in two decimal precision

The Attempt at a Solution

What do they mean by cencentration... n/V ?
3L=3Kg=3000g
NaCl...+...H₂O
250g ...3000g
58.8g...18g

No idea, there are many ways of exdpressing the concentration. It can be % w/w, % w/v, % v/v, molarity, molality, molar fraction... whatever. Are you sure there is no other information given? Some context?
