Molar mass of FE2O3=2(55.85)+3(16)=159.7
2.56g*1mol/159.7*2mol/1mol*55.85g/1mol=1.79g
Explanation:
I hope this helps Chemistry is so hard and I hate it
Answer:
The answer is 28 gram.
28 gram of Nitrogen gas are found in 22.4 l in Nitrogen gas
Answer: 8 Moles of Oxygen
Explanation: The formula shows that there are (exactly) 4 oxygen atoms in each mole or formula unit. Therefore 4 * 2.00 = 8.
Temperature is a measure of the average kinetic energy of the particles in the sample. This is the statement that defines the temperature of a sample of matter.
The temperature of a system is defined simply as the average energy of microscopic motions of a single particle in the system per degree of freedom.
The microscopic motions in a solid matter is the principal vibrations of the constituent atoms about their sites. In an ideal monoatomic gas, the microscopic motions are the translational motions of the constituent gas particles. In multiatomic gases, aside from translational motions, vibrational and rotational motions are included in the microscopic motions.
