30.5 g of sodium metal reacts with chlorine gas to produce sodium chloride. How much (in grams) chlorine gas must react with thi
Lena [83]

Answer:

Mass of chlorine = 47.22 g

Explanation:

Given data:

Mass of sodium = 30.5 g

Mass of chlorine= ?

Solution:

Chemical equation:

 2Na + Cl₂      →      2NaCl  

Number of moles of Na:

Number of moles = mass/molar mass

Number of moles = 30.5g/ 23 g/mol

Number of moles = 1.33 mol

Now we will compare the moles of Cl ₂ with Na from balance chemical equation.

                    Na            :              Cl ₂

                     2              :               1

                     1.33          :            1/2×1.33 = 0.665 mol

Mass of chlorine gas:

Mass = number of moles × molar mass

Mass = 0.665 mol × 71 g/mol

Mass = 47.22 g

etermine the molar concentration of magnesium ions in a solution formed by mixing 100.0 mL of 0.100 M MgCl, solution with 100.0
marysya [2.9K]

Answer:

Molar concentration of magnesium ions in the final solution is 0.2 M.

Explanation:

c=\frac{n}{V}

c = Concentration of the solution

n =   moles of the compound

V = volume of the solution in L

1) Molarity of MgCl_2 solution = 0.100 M

Volume of MgCl_2 solution = 100.0 mL = 0.1 L

Moles of MgCl_2 in 100 mL solution= n

0.100 M=\frac{n}{0.1L}

n=0.01 mol

MgCl_2(aq)\rightarrow Mg^{2+}(aq)+2Cl^-(aq)

1 mole of magnesium chloride gives 1 mol of magnesium ions and 2 moles of chloride ions.

Then 0.01 moles of magnesium chloride will give:

x=\frac{1}{1}\times 0.01 mol=0.01 mol magnesium ions.

2) Molarity of Mg_3(PO_4)_2 solution = 0.100 M

Volume of Mg_3(PO_4)_2 solution = 100.0 mL = 0.1 L

Moles of Mg_3(PO_4)_2 in 100 mL solution= n'

0.100 M=\frac{n'}{0.1L}

n'=0.01 mol

Mg_3(PO_4)_2(aq)\rightarrow 3Mg^{2+}(aq)+2PO_{4}^-(aq)

1 mole of magnesium phosphate gives 3 mol of magnesium ions and 2 moles of phosphate ions.

Then 0.01 moles of magnesium phosphate will give:

y=\frac{3}{1}\times 0.01 mol=0.03 mol magnesium ions.

After mixing both solutions:

Moles of magnesium ions = x + y = 0.01 mol + 0.03 mol = 0.04 mol

Total volume after mixing = 0.1 L + 0.1 L = 0.2 L

Molar concentration of magnesium ions in the final solution:[Mg^{2+}]

[Mg^{2+}]=\frac{0.04 mol}{0.2 L}=0.2 mol/L
