The expected outcome would be A. The reaction will speed up after adding a catalyst to a chemical reaction.
Hi , I’m really sorry because I just have the first question... so here it is :
So it is 0.52 mol .
Have a nice day .
<span>divide the 201g by the mol mass of the compound. Just add up the masses of the various element</span>
Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
Answer:
How many grams of H2O are in 1.0 mole of H2O?
18.02 grams
The average mass of one H2O molecule is 18.02 amu. The number of atoms is an exact number, the number of mole is an exact number; they do not affect the number of significant figures. The average mass of one mole of H2O is 18.02 grams.
