For this PreLab assignment we will assume all of the acid is the monoprotic acid acetylsalicylic acid (C9H8O4). [Note: for your

analysis in the PostLab you will subtract the moles of salicylic acid from the total acid content to determine the amount of acetylsalicylic acid]. How many moles of acetylsalicylic acid are in the 0.2001 g sample of your aspirin

Answer:

0.0011 moles

Explanation:

Recall that;

Number of moles = mass of substance/ molar mass of the substance

Mass of asprin = 0.2001 g

Molar mass of asprin = 180.158 g/mol

Number of moles =  0.2001 g/180.158 g/mol

Number of moles = 0.0011 moles

In Part B the given conditions were 1.00 mol of argon in a 0.500-L container at 18.0°C. You identified that the ideal pressure (

Answer:

4,38%

small molecular volumes

Decrease

Explanation:

The percent difference between the ideal and real gas is:

(47,8atm - 45,7 atm) / 47,8 atm × 100 = 4,39% ≈ <em>4,38%</em>

This difference is considered significant, and is best explained because argon atoms have relatively <em>small molecular volumes. </em>That produce an increasing in intermolecular forces deviating the system of ideal gas behavior.

Therefore, an increasing in volume will produce an ideal gas behavior. Thus:

If the volume of the container were increased to 2.00 L, you would expect the percent difference between the ideal and real gas to <em>decrease</em>

The arrows in the chart below represent phase transitions. Three bars are shown labeled Solid, Liquid, and Gas. They are connect
Setler [38]

The arrows that represent the phase transitions in which heat energy is gained is : (A). 1, 2 and 3

<h3>Meaning of phase transitions</h3>

Phase transitions can be defined as the changing of matter from one form to another due to the addition or gaining of heat or due to the removal or loss of heat.

Phase transitions in matter are majorly between three phases which are: Solid, Liquid and Gas.

In conclusion, The arrows that represent the phase transitions in which heat energy is gained is : (A). 1, 2 and 3
