B) Morrison and Franscioni's research done to create the Frisbee.
For the purpose we will here use the ideal gas law:
p×V=n×R×T
V= ?
n = 0.5 moleT= 273.15 K (at STP)
p= 101.325 kPa (at STP)
R is universal gas constant, and its value is 8.314 J/mol×K
Now when we have all necessary date we can calculate the number of moles:
V=nxRxT/p
V=0.5x8.314x273.15/101.325= 11.2 L = 11200 mL
Answer: D.
Answer:
T = 9.875K
Explanation:
The ideal gas Law is PV = nRT.
P = Pressure
V = Volume
n = amount of substance
R = 8.314 J/(K. mol)
T = Temperature in Kelvin
22g CO2
CO2 Molar Mass = 44g/mol
C = 12g/mol
O = 16g/mol
P = 0.8210atm
V = 50L
PV = nRT
0.8210 x 50 = 8.314 x 0.5 x T
41.05 = 4.157T
T = 41.05/4.157
T = 9.875K
B. do the experiment more than once
Explanation:
To do a multiple trials of an experiment, it is best to do the experiment more than once.
Experimental trials are mere replication of the procedures in an experiment.
- Most hypothesis on which experiments are based must be repeatable.
- When experiments are repeated through several trials, their accuracy is increased.
- Multiple trials clearly makes it easy to make meaningful deductions from an experimental process.
