makvit [3.9K]2 years ago
6 0
The formula of acetamide is C2H5NO
It contains 2 atoms of carbon 
The atomic mass of carbon is 12; therefore 2 atoms of carbon contains 24 g
The mass of 1 mole of acetamide is 59.07 g/mol
Therefore; the percentage of carbon in asetamide will be'
 =24/59.07 ×100
 = 40.63 %

What volume will 12.0 g of oxygen gas occupy at 25 c and a pressure of 52.7 kpa?
Stolb23 [73]
We can use the ideal gas law equation to find the volume occupied by oxygen gas
PV = nRT
where ;
P - pressure - 52.7 kPa
V - volume 
n - number of oxygen moles - 12.0 g / 32 g/mol = 0.375 mol
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - temperature - 25 °C + 273 = 298 K
substituting the values in the equation 
52 700 Pa x V = 0.375 mol x 8.314 Jmol⁻¹K⁻¹ x 298 K
 V = 17.6 L
volume of the gas is 17.6 L

Add a constant temperature when the volume of the gas is decreased what happens to its pressure
Margaret [11]

Answer:

<h2>Pressure will increase</h2>

Explanation:

At a constant temperature, the pressure of gas will increase proportional to the decrease in volume of the gas.

P1V1= P2V2

Decrease in volume result in increase in pressure as the equation has to hold true.
