Explanation:
if the line is short then the distance is short if its long then the distance is long
where the Avogadro's constant that relates the number of particles to their number, in the unit moles .
The molar mass of propanol- mass per mole propanol- can be directly deduced from its molecular formula with reference to a modern periodic table.
of propanol molecules would thus have a mass of
Answer:
B) 25g
Explanation:
Every reaction must follow the law of conservation of mass.
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Explanation:
This law was given by French chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
For example:
In given photosynthesis reaction:
6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂
there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.
In given example:
Water + sodium chloride → Product
15 g + 10 gram = 25 g
25 g = 25 g
