States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
![2.) Calculate the moles of KHP in flask #2.
\[
\text{moles KHP} = \frac{\text{grams KHP}}{\text{Molar Mass of KHP}} = \frac{(A2)}{204.22 \, \text{g/mol}}
\]
\[
\frac{1.009}{204.22 \, \text{g/mol}} = \boxed{(A11)}
\]
**Explanation:**
- This calculation involves finding the number of moles of potassium hydrogen phthalate (KHP) in a given flask.
- The formula used is:
\[
\text{moles KHP} = \frac{\text{grams of KHP}}{\text{Molar Mass of KHP}}
\]
- The given mass of KHP is 1.009 grams.
- The molar mass of KHP is 204.22 g/mol.
- You'll need to carry out the division to find the number of moles (denoted as (A11)).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd8e90fb2-40f2-4192-8084-b4b52249ad4c%2Fe302a4db-0337-4a77-beb2-433b3626d6d6%2F9y2onx_processed.jpeg&w=3840&q=75)
