Question

(3) You spin a number wheel that has 17-numbers 250 times. The random variable represents the winning numbers on each spin of the wheel.

Answer 1

Here is the Solution:

o We need to find out the volume of the gas after it cools to 25°C o We will use Charles's law equation, to solve this question. V V2 → Charles's law Ty Tz Where, .V1 = Is the volume at which CO2 are collected at 1200°C = 25 L V2 = Volume of the gas after it cools to 25°C = ? · T1 = Temperature at which coz is collected = 1200°C = 1200+ 273.15 = 1473.15 K -T2 = Is the final temperature = 25°C = 25 + 273.15 = 298.15 K Now, simply substitute the value is Charles's law equation and solve for V.. 25 L 1473.15 K 298.15 K =V2 x 1473.15 K = 298.15 K x 25 L v_298.15 K x 25 L →V2= 1473.15 K =V2 =5.0597 L OR V2=5.10 L Hence, the volume of the gas will be: 5.10 L
