It would be mol/dm^3
Formula of concentration: (no. of moles/volume of solution in dm^3)
1 cm^3 = 0.001dm^3
Hope this helped. :)
Hey are you from Calvert too? I got the same questions for the DBA
freezer and refrigerator too cold for most bacteria to grow .oven too hot for bacteria to survive
B) Sodium chloride
Plz mark me brainliest!
Hope this helps!
To calculate the partial pressure, we have to calulate the total pressure first.
Total pressure = (nRT/V)SO2 + (nRT/V)CO2
n is the number of moles
R is the general gas constant = 0.0821 L.atm/K.mole
T is the temperature in Kelvin
V is the total volume
n SO2 = mass/molar mass = 5/ 32 + 16*2 = 0.078125
n CO2 = mass/molar mass = 5/14+ 16*2 = 0.1
T = 50+273 = 323K
V = 750/1000 = 0.75 liters
Total Pressure = (0.078125*0.0821*323/0.75) + (0.1*0.0821*323/0.75) = 2.7623 + 3.535 = 6.298 atm
Partial pressure = x SO2 * Total Pressure = (no. of moles of SO2 / total no. of moles) * Total pressure = (0.078125/0.078125+0.1) * 6.298 = 2.762 atm.
