How many liters of 0.1107 M KCI contains 15.00 g of KCI (FW= 74.6 g/mol)

Chemistry

Number of moles:

n = sample mass / molar mass

n = 15.00 / 74.6

n = 0.2010 moles of KCl

Therefore:

Molarity = moles / Volume

0.1107 = 0.2010 / V

V = 0.2010 / 0.1107

V = 1.815 L

Answer:

1.81 liters of KCl solution

Explanation:

Molarity is expressed as:

Molarity=\frac{molesofsolute}{litersofsolution}

Solving for Liters of solution:

Liters of solution = \frac{molesofsolute}{Molarity} (1)

Using the molecular weight fo the KCl to find the moles of solute:

15.00gKCl*\frac{1molKCl}{74.6gKCl}=0.20molesKCl

Replacing in the formula (1):

Liters of solution = \frac{0.20molesKCl}{0.1107M}

Liters of solution = 1.81 liters

Suppose two scientists perform the same experiment separately, but their results are very different. What could they do to find
Lynna [10]
They should identify the confounding variable.

Some condition that is not examined by the scientist might alter the experiment result. That condition is called confounding variable. If the method of the experiment same but result is very different, there should be unidentified confounding variable. It could be air humidity, temperature, ventilation, light, time of the year or anything that might not be seen by naked eye.
Try to redo the experiment with controlling variable as much as possible.
