In an experiment, a student needs 250.0 mL of a 0.100 M copper (II) chloride solution. A stock solution of 2.00 M copper (II) ch
LekaFEV [45]

Answer : The volume of stock solution needed are, 12.5 mL

Explanation :

Formula used :

M_1V_1=M_2V_2

where,

M_1\text{ and }V_1 are the initial molarity and volume of copper (II) chloride.

M_2\text{ and }V_2 are the final molarity and volume of stock solution of copper (II) chloride.

We are given:

M_1=0.100M\\V_1=250.0mL\\M_2=2.00M\\V_2=?

Putting values in above equation, we get:

0.100M\times 250.0mL=2.00M\times V_2\\\\V_2=12.5mL

Hence, the volume of stock solution needed are, 12.5 mL

How many grams of KNO₃ should be used to prepare 2.00L of a .500 M solution ?
Svetradugi [14.3K]
<span>Volume = 2.00 L

Molarity = 0.500 M

M = n / V

0.500 = n / 2.00

n = 0.500 * 2.00

n = 1.0 mole KNO</span>₃<span>

Molar mass KNO</span>₃ = <span>101.1032 g/mol
</span>
1 mole ------ <span>101.1032 g
</span>1.0 mole ------ ?

mass = 1.0 * 101.1032 g / 1

mass = 101.1032 g of KNO₃

hope this helps!
