Answer:
2.39 moles
Explanation:
From the question given above, the following data were obtained:
Pressure (P) = 2.34 atm
Volume (V) = 25.6 L
Temperature (T) = 305 K
Number of mole (n) =?
NOTE: Gas constant (R) = 0.0821 atm.L/Kmol
The number of mole of CO₂ can be obtained by using the ideal gas equation as shown below:
PV = nRT
2.34 × 25.6 = n × 0.0821 × 305
59.904 = n × 25.0405
Divide both side by 25.0405
n = 59.904 / 25.0405
n = 2.39 moles
Thus, the number of mole of CO₂ is 2.39 moles.
The exact cause of attention deficit hyperactivity disorder (ADHD) isn't known. But it may run in families. Ongoing research is focused on finding the genes that cause a person to be likely to get ADHD. A mother's use of cigarettes, alcohol, or other drugs during pregnancy may increase the risk for ADHD.
