Answer:
12430mL of water must be added
Explanation:
To solve this question we need to convert the 20%w of CuSO₄ to molarity. Then, using the <em>diulution factor </em>we can find the amount of water required:
20g CuSO₄ / 100mL * (1mol / 159.609g CuSO₄) = 0.1253 moles / 100mL = 0.1253mol / 0.1L =
1.25M is the concentration of CuSO₄. To dilute this concentration to 0.01M, the dilution factor must be of:
1.25M / 0.01M = 125 times must be diluted the solution.
As the volume of the concentrated solution is 100mL, the total volume of the solution to have a 0.01M solution must be of:
100mL * 125 times = 12530mL is the final volume of the solution. That means the amount of water added must be of:
12530mL - 100mL =
<h3>12430mL of water must be added</h3>
Answer:
Iron is a metal.
Iron wool is made up of thin strands of
iron loosely bundled together.
Your teacher has attached a piece of
iron wool to a see-saw balance. At the
other end of the see-saw is a piece of
Plasticine.
Iron wool can combust. Your teacher is
going to make the iron wool combust by
heating it.
If there is a change in mass, the see-saw
will either tip to the left or to the right.
Explanation:
