Question

К 150 гр 10% раствора K2SO4 добавили 100гр воды.Определить процентную концентрацию сульфата кальция в растворе

Answer 1

С=150*0,1:250=0,06
0,06=6%
Ответ:6%

Answer 2

Calculation of the Concentration of Calcium Sulfate in the Solution

To determine the percentage concentration of calcium sulfate in the solution, we need to calculate the amount of calcium sulfate present in the solution and then express it as a percentage of the total solution mass.

Given information: - Mass of the 10% K2SO4 solution = 150 grams - Mass of water added = 100 grams

To calculate the concentration of calcium sulfate, we need to know the molar mass of calcium sulfate (CaSO4). The molar mass of CaSO4 is approximately 136.14 g/mol.

First, let's calculate the mass of calcium sulfate in the 10% K2SO4 solution: - The 10% K2SO4 solution contains 10 grams of K2SO4
