The percent composition  of this compound :

Mg = 72.182%

N = 27.818%

<h3> Further explanation </h3>

Given

9.03 g  Mg

3.48 g  N

Required

The percent composition

Solution

Proust stated the Comparative Law that compounds are formed from elements with the same Mass Comparison so that the compound has a fixed composition of elements

Total mass of the compound :

= 9.03 g + 3.48 g

= 12.51 g

The percent composition :

Mg : 9.03/ 12.51 g x 100% = 72.182%

N : 3.48 / 12.51 g x 100% = 27.818%

Find the % composition for each element in Zn(CIO3)2
bezimeni [28]

Zn = 28.15%

Cl = 30.53%

O = 41.32%

<h3>Further explanation</h3>

Given

Zn(CIO3)2 compound

Required

The % composition

Solution

Ar Zn = 65.38

Ar Cl = 35,453

Ar O = 15,999

MW Zn(CIO3)2 = 232.3

Zn = 65,38/232.3 x 100% = 28.15%

Cl = (2 x 35.453) / 232.3 x 100% = 30.53%

O = (6 x 15.999) / 232.3 x 100% = 41.32%

ikadub [295]

Answer:

"1 M" will be the right solution.

Explanation:

The given values are:

Number of moles,

= 2 moles

Volume of solution,

= 2000 mL

or,

= 2 L

Now,

The molarity of the solution will be:

=  \frac{Moles}{Liters}

On substituting the values, we get

=  \frac{2}{2}

=  1 \ M
