Answer:

d = 10490 kg/m³

Explanation:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m=mass

V=volume

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Given data:

Mass of box = 73430 Kg

Volume = 7 m³

density of box = ?

Solution:

d = m/v

d = 73430 Kg/7 m³

d = 10490 kg/m³

• Draw lewis dot structures for an atom of each of following elements:
marin [14]

Answer:

Explanation:

Lewis dot structures represent the symbol of an atom we're looking at and the number of valence electrons it has. This number is represented by the sum of dots around the symbol.

  • Potassium is in group 1A, this means it only has one valence electron, so we draw K with one dot in its Lewis diagram;
  • Argon is in group 8A, this means it has eight valence electrons, so we draw Ar with 8 dots around it in its Lewis diagram;
  • Silicon is in group 4A, this means it has four valence electrons, so we draw Si with 4 dots around it in its Lewis diagram;
  • Arsenic is in group 5A, this means it has five valence electrons, so we draw As with 5 dots around it in its Lewis diagram.

Those are represented in the image attached below:

A specific steroid has a λmax of 257 nm and a molar absorptivity ε of 11 , 500 L mol − 1 cm − 1 . What is the concentration of t
joja [24]

Answer:

7.83\times 10^{-6} M is the concentration of the compound in a solution.

Explanation:

Using Beer-Lambert's law :

Formula used :

A=\epsilon \times C\times l

Where:

A = absorbance of solution

C = concentration of solution

l = path length

\epsilon = molar absorptivity coefficient

We have:

C = ? , l = 1.00 cm, A = 0.090

\epsilon = 11,500 L/(mol cm)

C=\frac{A}{\epsilon l}=\frac{0.090}{11,500 L/(mol cm)\times 1.00 cm}

C=7.83\times 10^{-6} M

7.83\times 10^{-6} M is the concentration of the compound in a solution.
