If 45.0 mL of 6.00M HCl is added to 130 mL of H2O, Determine the molarity of the final solution. (show work)
Ivahew [28]

2.07 M is the molarity of the final solution if 45.0 ml of 6.00M HCl is added to 130 ml of H_{2}O.

Explanation:

Data given:

volume of HCl, V1 = 45 ml

molarity of the HCl solution, M1 = 6 M

final volume of the HCl solution after water is added, V2 = 130 ml

final molarity M2 =?

After the dilution, the molarity of the new solution can be found by using the formula:

M1V1 = M2V2

here M1 and V1 are the molarity and volume for concentrated solution, M2 and V2 represents the diluted solution's molarity and volume.

Applying the formula after rearranging the equation, we get

M2 = \frac{M1V1}{V2}

M2 = \frac{6X45}{130}

M2 = 2.07 M

The final molarity of the HCl solution is 2.07 M

4. How many molecules are in the following formula?<br> 3Fe2O3
serg [7]

Answer:

Option C, 3 molecule is correct

Explanation:

The formula is of Ferric oxide

3Fe2O3

The number 3 ahead the chemical formula represents the number of molecules of the given substance. In general the formula of iron (III) oxide is Fe2O3

Since there are three molecules of it hence the formula is written as 3Fe2O3

Option C, 3 molecule is correct
