you have a 25.2 l sample of gas at 1.25 atm and 25.0 degrees celsius. how many moles are present in this gas. for your answer, do not include units and provide your answer to three significant figures.

Explanation:

This is a direct application of the equation for ideal gases.

Where:

Solving for n:

Substituting:

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
