Answer:
1.2 x 10²³atoms
Explanation:
Given parameters:
Mass of CO(NH₂) = 12g
Unknown:
Number of Nitrogen atoms = ?
Solution:
Given compound;
CO(NH₂);
In;
1 mole of CO(NH₂), we have 1 mole of N
let us find the number of moles of CO(NH₂);
Number of moles =
Number of moles = = 0.2moles
Since
1 mole of CO(NH₂), we have 1 mole of N
0.2 mole of CO(NH₂) will have 0.2mole of N
1 mole of a substance contains 6.02 x 10²³ atoms
0.2 mole of N will contain 0.2 x 6.02 x 10²³ atoms = 1.2 x 10²³atoms
They will eventually reach equilibrium. But, before that, the thermal energy particles of the COLD milk will slow down the hot cocoa.
One atmosphere is equal to 101.3 kilopascals, the measurement of force that the atmosphere exerts at sea level. To convert 112 atmospheres to kilopascals, simply multiply the two together.
112 atm x (101.3 kPa/1 atm) = 11,345.6 kPa
/\
conversion factor
112 atmospheres is the same amount of pressure as 11,345.6 kilopascals.
Answer:
gas is the correct answer.
