What is the value of [oh–] in a 0.820 m solution of sr(oh)2?
aniked [119]
Strontium Hydroxide Ionizes as follow,

                                       Sr(OH)₂   →   Sr²⁺  +  2 OH⁻
So,
1 mole of Sr(OH)₂ produces 2 moles of Hydroxides,

If the concentration of 1 M Sr(OH)₂ produces 2 M OH⁻ ions then, 0.082 M Sr(OH)₂ will produce,

                                  [OH⁻]  =  2 × 0.082

                                  [OH⁻]  =  0.164 M

If 3.95 g of N2H4 reacts and produces 0.750 L of N2, at 295 K and 1.00 atm, what is the percent yield of the reaction?
adell [148]
Molar mass of N2H4 = 32 grams/mole 
<span>3.95 grams of  N2H4 = 3.95/32
                                  = 0.123 moles </span>

<span>This will produce 0.123 moles of N2 </span>
<span>Now,
From the gas law equation. </span>
<span>P.V = n x R x T </span>
<span>P = 1 atm (given)
V = </span><span>0.123</span><span> x 0.082057 x 295 </span>
<span>V = 2.97 Liters </span>

<span>Theoretical yield = 2.97 Liters.
Actual yield = 0.750 Liters </span>

percentage yield = (0.75/2.97) x 100 %
                           = 25.25 %

iren2701 [21]

Mass of Nd₂(SO₄)₃ : 2.653 g

<h3>Further explanation</h3>

Reaction

Nd₂Fe₁₄B + 17H₂SO₄ → Nd₂(SO₄)₃ + 14FeSO₄ + B + 17H₂

5 g Nd₂Fe₁₄B

MW = 2. 144,242 + 14. 55.845 + 10.811

MW = 288.484 + 781.83+10.811=1081.125 g/mol

mol :

\tt mol=\dfrac{mass}{MW}\\\\mol=\dfrac{5}{1081.125}=0.0046

mol Nd₂Fe₁₄B = mol Nd₂(SO₄)₃=0.0046

so mass of Nd₂(SO₄)₃ :

MW Nd₂(SO₄)₃ = 2.144.242+3.32,065+12.15,999

MW = 288.484+96.195+191.988=576.667 g/mol

\tt mass=mol\times MW\\\\mass=0.0046\times 576.667\\\\mass=2.653~g
