Answer:
28.01 percent
Explanation:
Iron (III) sulphate, , has 2 atoms of Fe.
One atom of Fe has a molar weight of 56. Hence, 2 atoms of Fe would have a total molar weight of 56 x 2 = 112 g/mol
Molar weight of = 399.88 g/mol
Percentage Fe in = 112/399.88 x 100%
= 28.01%
The percentage of iron is iron (III) sulphate is, therefore, 28.01 percent.
4.5 x 107 cm3
4.5 x 104 dm3
5.0 x 108 mm3
if you convert all of the following metrics to m^3. Then the first one is the largest number. I know this stuff did it last year
Nonpolar covalent bonds form when two atoms of the same element or different elements share electrons equally, resulting in a balanced charge distribution. Examples include Methane (CH4) and molecular oxygen (O2). Another case is the CO2 molecule, which is nonpolar because its polar bond moments cancel out.
This leads to a balanced distribution of charges in the molecule, making it nonpolar. Methane, for instance, consists of a carbon atom that shares four electrons equally with four hydrogen atoms, resulting in a bond where the difference in electronegativity between the carbon and hydrogen atoms is minimal.
Another case is CO₂ where the molecule, though consisting of polar bonds, is overall nonpolar because the geometric layout of the molecule allows for the bond moments to cancel each other out, hence no region of the molecule is more positive or negative than any other. Considering the geometry of the molecule is essential when determining the polarity of a molecule with more than one bond.

The mantle stretches down 2,890 kilometers, making it the Earth's thickest layer and the core that can be studied only by indirect means.
The layers of earth can be defined as the layer which is present inside the earth surface.
There are basically three different layers of earth.
Thus, the mantle stretches down 2,890 kilometers, making it the Earth's thickest layer and the core that can be studied only by indirect means.

Explanation:
The given data is as follows.
V = 250.0 ml, T = 58^{o}C = 58 + 273 = 331 K
n = 2.48 moles, P = ? , R = 0.082 atm L /K mol
Therefore, calculate the pressure using ideal gas equation as follows.
PV = nRT
P =
=
= 0.269 atm
Thus, we can conclude that pressure of the given gas is 0.269 atm.
