Calculate the volume in (L) of 1.13x10^5 grams of liquid sodium which has a density of 0.929g/cm3
Yuki888 [10]

The volume of the liquid sodium is 121.64 L

<h3>What is density? </h3>

The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as

Density = mass / volume

With the above formula, we can obtain the volume of the liquid. Details below

<h3>How to determine the volume of the sodium liquid</h3>
  • Mass of liquid = 1.13×10⁵ g
  • Density of liquid = 0.929 g/cm³
  • Volume of liquid =?

Density = mass / volume

Thus,

Volume = mass / density

Volume of liquid = 1.13×10⁵ / 0.929

Volume of liquid = 121636.17 cm³

Divide by 1000 to express in liter

Volume of liquid = 121636.17 / 1000

Volume of liquid = 121.64 L

In an analysis of the following reaction at a certain temperature,Br2(g) + Cl2(g) ⇌ 2BrCl(g)the equilibrium concentrations were
aev [14]

The equilibrium expression is Equilibrium constant =  \frac{concentration of product }{concentration of reactant}

Kc or equilibrium constant for this reaction is 0. 55 x 10^{2}

Explanation:

Br2(g) + Cl2(g) ⇌ 2BrCl(g)

Equilibrium constant =  \frac{concentration of product }{concentration of reactant}

Kc =[BrCl]^{2} \frac{[BrCl[2}{[Br]2[Cl]2}   equation 1

      the concentration of diatoms will be divided by 2

1.3 x 10^-2 is concentration of chlorine

0.45 x 10^-2 is concentration of bromine

1.6 ×10−2 is concentration of BrCl2

Putting the values in equation 1 to calculate equilibrium constant.

Kc=    \frac{[1.6 ×10−2]}{[0.45 x 10^-2] [1.6 ×10−2]}

Kc =   \frac{ 1.6 ×10−2}{2.9 x 10-4}

Kc= 0.55 x 10^2

equilibrium constant for this reaction is 0.55 x 10^{2}

the molar concentration or partial pressure of the gases is taken to find the equilibrium constant.
