Explanation:
To convert moles to particles or grams to particles, let us have a firm understanding of what a mole is.
A mole is the unit of measuring quantity of particles.
It is the amount of substance that contains the Avogadro's number of particles.
The particle can be atoms, molecules, formula units, electrons, protons, neutrons, etc.
So, to convert from moles to particles;
1 mole of a substance contains 6.02 x 10²³ particles
To convert from grams to particles;
First convert to moles;
number of moles = 
So, 1 mole of a substance contains 6.02 x 10²³ particles
Water containing carbonic acid and calcium
The answer is to increase the surface area of the solute.
You see it dissolves faster because there is a lot more water touching it when it is has a higher surface area.This can be achieved by crushing
The electron subshells in the atoms of group 5a elements discourage electron addition.
This is because the subshells in the group 5a elements are already half-filled, which is a more stable electronic configuration that that which would be achieved if another electron was added.
Meanwhile, group 4a elements' subshell becomes half-filled when an electron is added, making them somewhat stable. This means that they prefer electron addition.
Answer:
V = 56.816 cm³
Explanation:
Given that,
The measured value of the cylinder is 54.5 cm³
The percent error in the measurement of the volume is 4.25%
We need to find the actual volume of the cylinder.
Firstly, we can find the error in the calculation as follows :
It is mentioned in the problem that, the teacher told her that she was 4.25% too high in her determination of the volume. It would mean that,
Total volume = 54.5 + 2.316 = 56.816 cm³
Hence, the actual volume of the cylinder is 56.816 cm³.
