Answer:
49902.4 g/mol.
Explanation:
Using ideal gas equation,
PV = nRT
Where,
P = pressure
= 0.00144 atm
V = volume
= 0.01 l
T = absolute temperature
= 273 + 23.5
= 296.5 K
R = gas constant
= 0.0821 atm.l/K.mol
n = number of moles
n = (0.00144 * 0.01)/0.0821 * 296.5
= 5.92 x 10^-7 mol.
Molar mass = mass/number of moles
= 0.02952/5.92 x 10^-7
= 49902.4 g/mol.
Answer:
Net force= -5N+5N =0
Therefore there is no change in motion
Explanation:
180 K
V1/T1 = V2/T2
V1 = 500 mL
T1 = 300 K
V2 = 300 mL
Solve the equation for T2 —> T2 = V2T1/V1
T2 = (300 mL)(300 K) / (500 mL) = 180 K
A greenhouse gas is one that leads to global warming, by the absorption of infra-red radiation re-emitted by the ground. Common greenhouse gases include carbon dioxide and methane. Surprisingly, water vapour (which contains only oxygen and hydrogen) is also a greenhouse gas and can contribute to global warming.
