The lifetime of a human is approximately 71 years. Which of the following is this number closest to? Remember the following conv
1 answer:
2.2Giga
Explanation:
Given that the number of years = 71years
We need to convert this to seconds;
60s = 1 min
60 min = 1hr
24hr = 1 day
7 days = 1 week
52 weeks = 1yr
71 years x = 2,232,921,600s
This value is 2.2 x 10⁹s = 2.2Giga

<h3>What is the ideal gas equation?</h3>The ideal gas is one in which molecules do not attract or repel each other.Many gases like oxygen,nitrogen, carbon di oxide can be treated as the ideal gases as particular temperature and pressure.The real gases at high temperature and lower pressure can be treated as ideal gases.
The given data in the question is
Volume = 1.35 L
Pressure (P) = 750 torr
Temperature (T) = 17 °C = 17 + 273 = 290 K
Gas constant (R) = 62.396 L•torr/mol•K
The number of moles (n) =?
How to determine the number of moles:
The number of moles present can be obtained by using the ideal gas equation as illustrated below:
Divide both sides by RT
Hence, the number of moles of air present is 0.056 mole
