The answer is 297.14 g/mol
Contour plowing is the practice of plowing fields along the curves of a slope.<span />
The volume of 3.40 mol of gas at 33.3 C and 22.2 atm of pressure is 3.85 liter of gas. This problem can be solved by using the PV=nRT or V= nRT/V equation which is the relation between the molar volume, the temperature, and the pressure of gas. In this formula, P is the pressure, R is the universal gas constant ( 0.0821 atm L/mol K), n is the molecule amount, V is the molecular volume, and T is the temperature. The temperature used in this formula must be in Kelvin, therefore we have to convert the Celcius temperature into Kelvin temperature (33.3 C = 306.45 K).
<span>The calculation for the problem above: 3.4*0.0821*306.45/22.2 = 3.85 liter of gas.</span>
<span>Spontaneous reactions need to be discovered first. Also, if reagents are transferred to the other cups used in the tests, it could contaminate them, leading to different colors being seen and the test results being invalid. Doing the reagent tests last ensure that the cups and reagents are only used on the substances that they are intended to.</span>
