The number of moles of the gas is to be calculated. Concept Introduction: The Ideal GasLaw is a combination of Charles’s law, Boyle’s Law and Avogadro’s Law . The Charles’s law states the relation between volume and temperature. According to Charles’s law, the volume is directly proportional to temperature. The Boyle’s law states the relation between pressure and volume. According to Boyle’s Law, the pressure is inversely proportional to volume. The Avogadro’s law states the relation between volume and number of moles. According to Avogadro’s Law, the volume is directly proportional to a number of moles. Therefore, the Ideal Gas Law combines the three laws to give the equation as: V ∝ T P ∝ 1 V V ∝ n V ∝ n T P The proportionality sign is replaced with an equal sign by multiplying the above equation with a proportionality constant called the Ideal Gas constant, R . V = n R T P Here, V , T , P , R are volume, temperature and pressure and ideal gas constant respectively.

Interpretation Introduction

Interpretation:

The number of moles of the gas is to be calculated.

Concept Introduction: The Ideal GasLaw is a combination of Charles’s law, Boyle’s Law and Avogadro’s Law.

The Charles’s law states the relation between volume and temperature. According to Charles’s law, the volume is directly proportional to temperature.

The Boyle’s law states the relation between pressure and volume. According to Boyle’s Law, the pressure is inversely proportional to volume.

The Avogadro’s law states the relation between volume and number of moles. According to Avogadro’s Law, the volume is directly proportional to a number of moles.

Therefore, the Ideal Gas Law combines the three laws to give the equation as:

V∝TP∝1VV∝nV∝nTP

The proportionality sign is replaced with an equal sign by multiplying the above equation with a proportionality constant called the Ideal Gas constant, R.

V=nRTP

Here, V,T,P, R are volume, temperature and pressure and ideal gas constant respectively.

What kind of relationship is this? How do you know? (see page 276 text) the design of the beaker is a uniform cylinder the volume of liquid increases evenly with its height resulting in a linear relationship. What volume would you predict for 10.0 cm of water? Explain how you arrived at your answer. Use the data table and the graph to assist you in answering the question. 4.

In the video, we looked at the absorbance of a certain substance and how it varies depending on what wavelength of light we are looking at. Below is a similar scan of a different substance. What color BEST describes how this substance will appear? Absorbance (AU) Violet Blue Green Orange 1.2 1.0- 0.8- 0.6- 0.4- 0.2 0.0 450 500 550 600 650 700 Wavelength (nm) violet indigo blue green yellow orange red Red O Cannot tell from this information In the above graph, what causes -450 nm wavelength of light to have a higher absorbance than light with a -550 nm wavelength? Check all that are true. The distance the light travels is different The different data points are for different substances The concentration is different at different times in the experiment Epsilon (molar absortivity) is different at different wavelengths
