Answer:
9.15 atm
Explanation:
Ideal gas equation of state PV=nRT
P in hPa, V in L, n in mol, R is a constant which is 83.1 hpa*L/mol*k, T in kelvin.
Plug in all the number, and we will get:
P*6.21=2.02*83.1*343
P =9271.6(in hpa)=9.15 atm
Answer: 7.90 g/cm^3
Explanation:
Density = Mass / Volume
The first step is to find the volume by multiplying the three measures of the cube that have been provided.
3.50 x 0.755 x 2.25 = 5.95 cm^3
Now we can plug the numbers into our equation.
Density = 47.0g / 5.95 cm^3
Density = 7.90 g/cm^3
Answer:
Helium, this noble gas has the least density at STP
