Let the total mass of compound is 100g
The mass of each element will be
Al = 22.10 g
P = 25.40 g
O = 52.50 g
In order to determine the molecular formula we will calculate the molar ratio of the given elements
Atomic weight of Al : 27 g/ mol
Atomic weight of P : 3 1g /mol
Atomic weight of O : 16 g /mol
Moles of Al = mass / atomic mass = 22.10 / 27 = 0.819
Moles of P = mass / atomic mass = 25.40/ 31 = 0.819
Moles of O = mass / atomic mass = 52.50/ 16 = 3.28
Now we will divide the moles of each element with the lowest moles obtained to obtain a whole number ratio of moles of each element present
moles of Al = 0.819 / 0.819 = 1
moles of P = 0.819 / 0.819 = 1
moles of O = 3.28 / 0.819 = 4
So the empirical formula will be : AlPO4
Answer: A Bronsted-Lowry acid is defined as a substance that acts as a proton donor.
Explanation:
A substance that is able to donate a proton or hydrogen ion to another substance is a Bronsted-Lowry acid.
For example, HCl is a Bronsted-Lowry acid as it dissociates to give a hydrogen ion.
Thus, we can conclude that a Bronsted-Lowry acid is defined as a substance that acts as a proton donor.
<span>There
are a number of ways to express concentration of a solution. This includes
molarity. Molarity is expressed as the number of moles of solute per volume of
the solution. We calculate as follows:

2.5 M HCl = 2.5 mol HCl / L soln
0.306 mol HCl / 2.5 mol HCl/L son = 0.1224 L soln needed
M1V1 = M2V2
18 M(V1) = 2.5 M(0.1224 L)
V1 = 0.017 L of the 18 M solution
i mean it can be true and it cant at the same time. i mean medicine doesn't always work on a person. but it is said that medicine that is in powder form is more efficient.
but i believe its D or A
<u>Answer:</u>
An example of a capital good is "the government will open another public school in the area".
<u>Explanation:</u>
A capital good or complicated products and systems or (CoPS) is a reliable commodity used in the manufacturing of goods and services. These are one of three kinds of consumer commodities, while the other two are property and labor.
The three are also commonly referred to as primary production factors.They are recorded on a company's balance sheet as assets, and can be depreciated over time. Capital goods instances include furniture, buildings, machinery, equipment and fixtures.
