Volume of the nitrogen gas = 49.8 L
<u>Explanation:</u>
It is given that the pressure, number of moles and temperature of nitrogen gas, and gas constant value being constant and it is taken as 0.08206 L atm mol⁻¹K⁻¹.
Temperature = T = 75°C = 75 + 273 = 348 K
Pressure = P = 0.992 atm
Number of moles = n = 1.73 moles
We have to use the ideal gas equation, PV = nRT, and rearranging the equation to get Volume in litres.
V =
=
= 49.8 L
So the volume of Nitrogen gas = 49.8 L
Answer:
The velocity of the particle is 2 m/s,
Explanation:
Kinetic energy is defined as energy of the body due to its motion. It is given by :
Where :
m = mass of the object
v = velocity of the object
We have , particle with mass m and its kinetic energy is twice its mass.
And unit of velocity are m/s , so the velocity of the particle is 2 m/s.
Answer:
Explanation:
Hello,
In this case, for each nitrate-based salt, we compute the nitrate moles as shown below:
We notice calcium nitrate has two moles of nitrate ion, sodium nitrate has one and aluminium nitrate has three. Hence we add the moles to obtain the total moles nitrate ion:
Finally, we compute the molarity:
Regards.
