What is the value of [oh–] in a 0.820 m solution of sr(oh)2?

1 answer:

4 0

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

Iron(II) sulfide has a primitive cubic unit cell with sulfide ions at the lattice points.

masya89 [10]

We have that the the density of FeS is mathematically given as

$\phi=2.56h/cm^3$

From the question we are told

Iron(II) sulfide has a primitive <em>cubic</em> unit cell with <em>sulfide</em> ions at the <em>lattice points.</em>

The ionic radii of iron(II) ions and sulfide ions are 88 pm and 184 pm, respectively.

What is the density of FeS (in g/cm3)?

<h3>Density</h3>

Generally the equation for the Velocity is mathematically given as

$V_c=a^3=(2\pi Fe^{2+}+2\pi S^{2-})^3\\\\Therefore\\\\V=a^3(2\pi*0.088+2\pi 0.184)^3\\\\V=16.98*10^{-23}\\\\Therefore\\\\\phi=n\frac{PFeion+PSion}{VNa}\\\\\phi=3*\frac{55.85+32}{16.9*10^{-23}*6.023*10^{23}}$

$\phi=2.56h/cm^3$

$\phi=2.56h/cm^3$
