PV = nRT —> n = PV/RT

P = 2.90 atm
V = 4.80 L
R = 0.08206 L atm / mol K
T = 62.0 + 273 = 335 K (make sure you convert from celsius to kelvin)

n = (2.90 • 4.80) / (0.08206 • 335) = 0.506 moles of gas

carbon disulfide is formed by the reaction of coke (carbon) with sulfur dioxide. how many moles of cs2 will be generated if 8.0

Murrr4er [49]

5C₂ + 4SO₂ ------> 2CS₂ + 8CO

mole ratio of C₂ : CS₂
=   5 : 2

∴ since C₂ contains 8 moles

then CS₂ contain    $( \frac{8}{5} ) * 2$ moles

= 3.2 moles
