How many grams of k2so4 would you need to prepare 1500 g of 5.0% k2so4 solution?

Answers

Answer 1
Answer: Data Given:
                                  % w/w  =  5 %

                    Solution weight  =  1500 g

                       Solute weight  =  ?

Formula Used:
                            % w/w  =  (Mass of Solute / Mass of Solution) × 100

Solving for Mass of Solute,
         
                       Mass of Solute  =  (% w/w × Mass of Solution) ÷ 100

                       Mass of Solute  =  (5 × 1500 g) ÷ 100

                       Mass of Solute  =  75 g K₂SO₄

Which statements are true concerning mineral formation? Check all that apply. The slower the cooling, the larger the crystals. The faster the cooling, the smaller the crystals. Crystals formed from magma are smaller than crystals formed from lava. Minerals can only form in solutions when the solution is heated deep underground. When a solution cools, elements and compounds leave the solution and crystallize as minerals. Minerals formed from hot water solutions can form narrow channels in the surrounding rock.
