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

Answers

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

What is the mass of 225 cm ^3 of ethanol? ethanol has a density of 0.789 g/cm^3

Answers

Answer:

177.53 grams

Explanation:

To find this, change the density equation from d=(m)/(v) to dv=m , doing this will allow you to multiply your given density (0.789 g/cm^3) by your given volume (225cm^3), giving your mass of 177.53 grams.

Fireworks exploding in the sky and giving off light are an example of a(n) _____. a. exothermic change
b. change in mass
c. physical change
d. endothermic change

Answers

Exothermic change. Because the firework when it exploded, released energy in the form of light. In exothermic changes energy is released, and in endothermic changes energy is absorbed.

- This wouldn't be a physical change, but instead a chemical change. A clue that it is a chemical change is that energy was given off.

the answer is A exothermic change
