Mathematical formula of Ideal Gas Law is PV=nRT
where: P-pressure,
V-volume
n-number of moles; m/MW
T-Temperature
m-mass
d-density ; m/V
MW-Molecular Weight
R- Ideal Gas constant. If the units of P,V,n & T are atm, L, mol & K respectively, the value of R is 0.0821 L x atm / K x mol
Substituting the definitions to the original Gas equation becomes:
d= P x MW / (RxT)
Solution : d= .90atm x 28 g/mol (CO) / 0.0821Lxatm / mol x K x 323 K
d = 25.2 g / 26000 mL
d = .0.00096 g/mL is the density of CO under the new conditions
Answer:
17 mc/L
Explanation:
We habe heat that is taken by the ice for it to melt to be equal to the heat given by water.
ML = mc(290K - 273K)
ML = mc 17
Then we divide through by L
M = 17 mc/L
Please note that 273k as we have used in thIs solution is the temperature at which we can have water to freeze
Therefore the minimum mass of required ice = 17 mc/L
Answer:
two may be the answer (2)
Answer:
The values are:
6.55 mmHg
0.00862 atm
Explanation:
This is all about unit conversion
760 mmHg = 760 Torr
1 atm = 760 Torr
6.55 Torr . 760 mmHg / 760 Torr = 6.55 mmHg
6.55 Torr . 1 atm / 760 Torr = 0.00862 atm
