Answer:
5.7 grams is the mass carbon dioxide gas inside a 3.0-L balloon.
Explanation:
Using ideal gas equation:
PV = nRT
where,
P = Pressure of carbon dioxide gas =
V = Volume of carbon dioxide gas = 3.0 L
n = number of moles of carbon dioxide gas = ?
R = Gas constant = 0.0821 L.atm/mol.K
T = Temperature of carbon dioxide gas =0°C = 0+273= 273 K
Putting values in above equation, we get:
Mass of 0.13 mole carbon dioxide gas :
= 0.13 mol × 44 g/mol = 5.7 g
5.7 grams is the mass carbon dioxide gas inside a 3.0-L balloon.
Answer:
Use the equation Q = mc∆T
Q =(m)(c)(∆T)
=(22.0g)(4.184J/g°C)(75°C)
=6903.6J
=6900J (Final result)
