Well, the molar mass of acetone would be
3(12.011)+6(1.008)+15.999 , which cleans up to be 58.08 grams.
out of this total, 3(12.011), or 36.033 grams are carbon
So, to find the percent, you do part over whole
36.033/58.08, which equals 0.6204 with significant figures
multiply that by 100 to get 62.04%
Hope that helps!
Answer:
3.3 cm³
Explanation:
Use the density formula, d = m/v, to solve for the volume:
2.7 = 9.0/v
2.7v = 9.0
v = 3.3 cm³
The equation for this is:

Answer:
To really 'see' inside the atom and detect fundamental particles we need to go beyond visible light and bounce particles off the smallest building blocks of the Universe to 'observe' them. This session introduces students to the scientific process—how scientific methods and theories are updated and develop as new evidence and information is collected.
Explanation:
Answer:
, Kp = 0.08967
, Kp = 2.3×10³⁰
Explanation:
The relation between Kp and Kc is given below:
Where,
Kp is the pressure equilibrium constant
Kc is the molar equilibrium constant
R is gas constant
T is the temperature in Kelvins
Δn = (No. of moles of gaseous products)-(No. of moles of gaseous reactants)
For the first equilibrium reaction:
Given: Kc = 2.2
Temperature = 299 K
R = 0.082057 L atm.mol⁻¹K⁻¹
Δn = (2)-(2+1) = -1
Thus, Kp is:
<u>Kp = 0.08967 </u>
For the second equilibrium reaction:
Given: Kc = 2.3×10³⁰
Temperature = 299 K
R = 0.082057 L atm.mol⁻¹K⁻¹
Δn = (2)-(2) = 0
Thus, Kp is:
<u>Kp = 2.3×10³⁰</u>
