The density in lbs/in³ units : 0.697
<h3>Further explanation</h3>
Given
Density of gold is 19.3 g/cm³
Required
Conversion to lbs/in³
Solution
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
Density formula:
Conversion factor
1 g = 0,00220462 lbs
1 cm³ = 0,0610237 in³
So the density :
Molarity can be defined as the number of moles of solute in 1 L of solution.
M = n/V
Where M is the molarity of the solution (M or mol/L), n is the moles of the solute (mol) and V is the volume of the solution (L).
Here, solute is KF.
n = <span>0.250 mol
</span>V = 0.500 L
M = ?
By applying the formula,
M = 0.250 mol / 0.500 L
M = 0.500 mol/L
Hence, the molarity of KF solution is 0.500 mol/L.
Explanation:
The condensed formula of a molecule is the formula where the symbols of atoms are listed in order as they appear in the molecule's structure with bond dashes omitted or limited.
The structural formular however, showed how the atoms are connected.
The condensed formular is given as; HOCH2COCH2OH
The condensed formular was gotten by writting out the elemnts in the order that they appear in.
The stuctural formular is shown in the attachement.
Answer:
The energy of a photon depends on the frequency of the emission.
Explanation:
E = hν
where E is the energy of a photon, ν is the frequency of photon and h is Planck’s constant.
Energy of a photon is quantized and is directly proportional to the frequency of the emission.
Quantized energy of a photon explained the photoelectric effect. It was proven that light not has wave nature but particle nature as well. This later gave rise to wave particle duality of light waves.
Answer:
D
Explanation:
The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them. This means that the force of gravity increases with mass, but decreases with increasing distance between objects.
