concentration of the contact solution = 3 %

Explanation:

We have the following data:

10.7 g of hydrogen peroxide H₂O₂

355 g of solution

To calculate the concentration of the contact solution we use the following formula:

concentration = (mass of solute / mass of solution) × 100

concentration of the contact solution = (10.7 / 355) × 100

concentration of the contact solution = 3 %

How many Liters of space will a 70.0g sample of CO2 occupy?
Tanzania [10]

Answer:

  35.6 liters at STP

Explanation:

The molar mass of carbon dioxide is about 44.01 g/mol. The volume of a mole of ideal gas at STP is 22.4 L, so the volume of 70.0 g will be ...

  (70.0g)/(44.01 g/mol)·(22.4 L/mol) ≈ 35.6 L

What are the controlled variables for water of crystallization experiment?
yarga [219]

Given what we know, we can confirm that as with any experiment, the control variable will be the one that through each trial of the experiment, no matter how many times it is performed, stays constant.

<h3>What is a controlled variable?</h3>
  • A variable that remains constant through an experiment.
  • They are used to compare results to the normal condition.
  • They are also used to isolate the changes to one factor at a time and thus know its exact effects on the outcome.
  • This increases the accuracy of the data and the subsequent conclusion.

Therefore, we can confirm that if a variable stays constant through each phase and trial of an experiment, it is considered to be a controlled variable and is useful in order to increase the accuracy of the conclusion.

Given 0.02 of KF, how many liters of solution are needed to make a 7.2 solution?
Dmitry_Shevchenko [17]

Answer:

1/360

Explanation:

let x = liters

molarity=moles of solute/liters of solution, 7.2=0.02/x or 7.2=(1/50)(1/x), 7.2(50)=(1/x), 360(x)=1, x=1/360
