Answer:
must usExplanation:This question refers to the study of gases. To solve it, initially we e the following expression:
P × V = n × R × T
where P is the pressure (Pa), V is the volume (m³), n is the number of moles in the sample, R is the universal gas constant and T is the temperature (K). Transforming the units according to the equation, we have:
P = 2 × 10 ^ 5 Pa
V = 8/1000 = 0.008 m³
T = 27 + 273 = 300 K
Substituting in the equation, we have:
2 × 10 ^ 5 × 0.008 = n × 8.0 × 300
n = 0.667 moles
Finally, we use the following expression, which relates number of moles and sample mass:
m = M × n
where m is the mass (g) and M is the molar mass (g / mol). Thus, the mass of this gas is:
m = 28 × 0.667
m = 18.67 g

Explanation:
Pour mes vacances de rêve..
Imagine you are going on a vacation. Use le futur proche (aller + infinitive) to describe where you are going to go, and what you are going to do. Start out by saying that you are going to go to a certain place for vacation in the near future (Je vais aller...), and use your imagination to create a minimum of 5 sentences in French to record.
Example: Pour mes vacances de rêve je vais nager aux tortues marines.
Your response needs to be at least 30 seconds in length in French.
You will be graded on (a) appropriate use of grammar and vocabulary, (b) completeness and detail of the response, and (c) pronunciation.
