Given :
0.26 mole of
and 0.35 L of water.
To Find :
The molarity of a solution of
made by mixing 0.26 mole of potassium
phosphate with water up to 0.35 L .
Solution :
We know, molarity is given by :
![M = \dfrac{number \ of \ moles }{Volume \ in \ Liter}\\\\M = \dfrac{0.26}{0.35}\ M\\\\M = 0.743 \ M](https://tex.z-dn.net/?f=M%20%3D%20%5Cdfrac%7Bnumber%20%5C%20of%20%5C%20moles%20%7D%7BVolume%20%5C%20in%20%5C%20Liter%7D%5C%5C%5C%5CM%20%3D%20%5Cdfrac%7B0.26%7D%7B0.35%7D%5C%20M%5C%5C%5C%5CM%20%3D%200.743%20%5C%20M)
Therefore, the molarity of
solution is 0.743 M.
Answer: Hydrocarbon fuels like methane (CH4) burn in the presence of oxygen to produce carbon dioxide and water. This process of combustion releases energy. When energy is released during the course of a chemical reaction, it is said to be an EXOTHERMIC reaction.
Explanation:
(3.500 mol MgO)(40.3044g MgO/1mol MgO)
=141.0654
Answer:
Classification is important because it allows scientists to identify, group, and properly name organisms via a standardized system (Linnaeus Taxonomy); based on similarities found in the organisms DNA/RNA (genetics), Adaptations (Evolution), and Embryonic development (Embryology) to other known organisms to better.
Hope I helped!!
Assuming ideality:
PV=nRT
Pv= (mass/molarmass)RT
Solve for the mass :-)
