6.022 x 10 23 titanium atoms
In 47.88 grams of titanium, there is one mole, or 6.022 x 1023 titanium atoms.
Hope this helps :)
Answer:
265.2amu
Explanation:
Given parameters:
Atomic mass = 254.9amu
Abundance of isotope 1 = 72%
Atomic mass of isotope 1 = 250.9amu
Abundance of isotope 2 = 100 - 72 = 28%
Unknown:
Atomic mass of isotope 2 = ?
Solution:
To find the atomic mass of isotope 2, use the expression below:
Atomic mass = (abundance of isotope 1 x atomic mass of isotope 1) + (abundance of isotope 2 x atomic mass of isotope 2)
Now insert the parameters and find the unknown;
254.9 = (0.72 x 250.9) + (0.28 x Atomic mass of isotope 2)
254.9 = 180.648 + 0.28x atomic mass of isotope 2
254.9 - 180.648 = 0.28x atomic mass of isotope 2
74.25 = 0.28 x atomic mass of isotope 2
Atomic mass of isotope 2 = 265.2amu
Answer:
unsaturated
Explanation:
All solutions have a definite capacity of dissolving solute in it.
Unsaturated solutions are the solutions which contain less amount of solute than the maximum capacity of dissolving the solute. If more amount of solute is added in such a way a point is reached where addition of more solute cannot be dissolved. The solution is known as saturated solution.
Amount dissolved > Maximum solubility limit, the solution is saturated.
Amount dissolved < Maximum solubility limit, the solution is unsaturated.
If the amount of the salt exceeds the solubility limit, then the solution is saturated solution. If it is less than the limit given, then it is unsaturated solution.
The solubility = 0.667 grams per liter
Amount dissolved = 0.502 grams per liter
Since,
Amount dissolved < Maximum solubility limit, the solution is unsaturated.
