Answer:
1.02KPa
Explanation:
The following were obtained from the question:
V1 = 1550mL
P1 = 70.26kPa
T1 = 480°C = 480 + 273 = 753K
T2 = -237°C = - 237 + 273 = 36K
V2 = 5114mL
P2 =?
The final pressure can obtain as follows:
P1V1/T1 = P2V2/T2
(70.26x1550)/753 = (P2x5114)/36
Cross multiply to express in linear form as shown below:
P2 x 5114 x 753 = 70.26 x 1550 x 36
Divide both side by 5114 x 753
P2 = (70.26x1550x36)/(5114x753)
P2 = 1.02KPa
Therefore, the final pressure is 1.02KPa
Answer:
The molecular weight of CO is 28.01g/mole.
Hey there !
Given the reaction:
N2 + 3 H2 = 2 NH3
At constant pressure and temperature ,volume is proporcional to moles:
Theoretical moles of N2 and H2 => 1:3
Theoretical volume of N2 and H2 => 1:3
Experimental volume of N2 and H2 => 3.0 L : 4.0 L
0.75 : 1 = 2.25 : 3
Since N2 is in excess reactant , H2 is the limiting reactant
Therefore:
volume of NH3 is 2/3 * Volume of H2
= 2/3 * 4.0 = 2.66 L
Hope that helps!
NaHCO3 = No. of atoms are 1 sodium + 1 Hydrogen + 1 carbon + 3 oxygens = 6 atoms per molecule.
so a total of 3 oxygens
