Answer:
1.5M
Explanation:
Molarity = moles/volume
0.60 mol / 0.40 L = 1.5 M
The answer would be C. It looks most like it I believe
PV = nRT
Where:
P = pressure in atm = 700/760 = 0.9211atm
V = volume = 8.29L
R = gas constant, 0.08206 atm-L/mol-K
T = temperature in Kelvin = 200 + 273 = 473
n = numbers of moles = Mass/molar mass
mass of the compound = 30.5
we can rewrite the equation above as
PV = (Mass)/(Molar mass) * RT
