Answer:
23.76g
Explanation:
To solve for the mass of carbon dioxide (CO2), let us first obtain the number of mole of CO2.
From the question, the following were obtained:
V = 8.13L
P = 204kPa = 204000Pa
Recall: 101325Pa = 1atm
204000Pa = 204000/101325 = 2atm
T = 95°C = 95 + 273 = 368K
R = 0.082atm.L/K/mol
n =?
PV = nRT
n = PV /RT
n = 2 x 8.13/ 0.082 x 368
n = 0.54mole
Now let us convert 0.54mole of CO2 to gram. This is illustrated below:
Molar Mass of CO2 = 12 + (16x2) = 12 + 32 = 44g/mol
Number of mole of CO2 = 0.54mole
Mass of CO2 =?
Number of mole = Mass /Molar Mass
Mass = number of mole x molar Mass
Mass of CO2 = 0.54 x 44
Mass of CO2 = 23.76g
Answer:
polar beacuse there is no way its non polar.
Mass is how much matter is in an object. Volume is how much space an object occupies. Density is the amount of mass in a volume.
Have a nice day, brainliest would be fantastic
2 Al + 3 H₂SO₄ = Al₂(SO₄)₃ + 3 H₂
2 moles Al -------- 3 moles H₂SO₄
4.4 moles Al ------ ?
moles H₂SO₄ = 4.4 x 3 / 2
moles H₂SO₄ = 13.2 / 2
= 6.6 moles of H₂SO₄
hope this helps!
Electron requires energy to move from ground state to excited state(higher energy levels). Hence option 1 is correct. Hope this helps!
