Molarity is calculated by using following formula,
Molarity = Moles / Volume
Data Given:
Moles = 23 moles
Volume = 100 ml ÷ 1000 = 0.1 L
Putting values in eq. 1,
Molarity = 23 mol / 0.1 L
Molarity = 230 mol/dm³
Result:
When 23 mol of solute is dissolved in a solvent to make a solution of 100 ml, then it will have a Molarity of 230 mol/dm³.
Answer:
I think the answer is C- radiation
Explanation:
If its not C its A Hope this helps forgive me if i'm wrong :/
Its C, Outermost Electrons.
Answer:
C
Explanation:
inertia
inertia is the reluctance of an object at rest or moving to change its state of rest or motion
because the car was moving, the dummy moves with the speed of the car..so when the crash happened the dummy continued to move..it was feeling reluctant to come to rest so was moving
Answer:
Average atomic mass = 14.0067 amu.
Explanation:
Given data:
Abundance of 1st isotope = 99.63%
Atomic mass of 1st isotope = 14.003 amu
Abundance of 2nd isotope = 0.37%
Atomic mass of 2nd isotope = 15.000 amu
Solution:
Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) / 100
Average atomic mass = (99.63×14.003)+(0.37×15.000) /100
Average atomic mass = 1395.119 + 5.55 / 100
Average atomic mass = 1400.67 / 100
Average atomic mass = 14.0067 amu.
