In this case, we are going to assume that there are 100 atoms to make things easier.
Let R% be the abundance of n-15. With this in mind, we calculate the abundance of n-14 to be 100%-R%
14.0031*(100-R)% + 15.001 * R%= 14.00674
In this case, we can delete or ignore the % sign since we do not want to carry it around, however, we need to keep in mind that the final answer is in %
14.0031*(100-R) + 15.001 * R= 14.00674
1400.31-14.0031R+15.001R=1400.674
0.9979R=0.364
R=0.3648
Then, the abundance of n-15 is 0.3648%
Elements which composed of an equal amount of three components protons, neutrons and electrons are considered neutral elements. example of neutral elements are hydrogen, helium, lithium and beryllium...
Answer:
NaOH and HCl
Explanation:
The reaction of sodium hydroxide, NaOH, with hydrochloric acid, HCl, produces NaCl and water.
0.04 m urea > 0.03 m CuSO4 > 0.01 m AgNO3.
<h3>What is colligative property?</h3>
- Colligative properties in chemistry are those of a solution that depend on the amount of solute particles to solvent particles in a solution rather than the makeup of the individual particles.
- The number ratio can be connected to the several units used to measure a solution's concentration, including molarity, molality, normalcy (chemistry), etc.
- For ideal solutions, which are ones that have thermodynamic properties similar to those of an ideal gas, and for diluted actual solutions, the assumption that solution properties are independent of the type of solute particles is exact.
<h3>What factors affect colligative properties?</h3>
- A property of a solution is said to be collative if it depends simply on the proportion of solute to solvent particles in the solution and not on the nature of the solute.
