Question

ПОМОГИТЕ РЕБЯТА!!!!!!! Обчисліть масу води і кухоної солі необхідно для приготування 150г розчину з масовою часткою солі 10%

Answer 1

150г - 100%
х - 10%
По пропорции х= 150*10:100 = 15г
Значит, нужно взять 15г воды и (150-15=135г) воды.

Answer 2

Calculating the Mass of Water and Table Salt for a 150g Solution with 10% Mass Fraction of Salt

To calculate the mass of water and table salt needed to prepare a 150g solution with a 10% mass fraction of salt, we can use the following formula:

Mass of solute = (Mass fraction of solute / 100) * Total mass of solution

Using this formula, we can calculate the mass of water and table salt required.

Calculating the Mass of Table Salt:

The mass fraction of salt is given as 10%, and the total mass of the solution is 150g. Using the formula, we can calculate the mass of table salt
