The molecular formula shows the exact number of molecules. Therefor, the empirical formula is the simplest formula of the molecular formula
Answer:
88,7 mL of solution
Explanation:
Molarity (Represented as M) is an unit of chemical concentration that is defined as the ratio between moles of solute per liters of solution, that is:
Molarity = moles of solute / Liters of solution
If molarity of KCN solution is 0,0820M and moles of KCN are 7,27x10⁻³ moles:
0,0820M = 7,27x10⁻³ moles / Liters of solution
Liters of solution = 0,0887L = <em>88,7 mL of solution</em>
I hope it helps!
Answer:
0.3758moles
Explanation:
moles of kcl = mass of kcl/ molar mass of kcl = 28/74.5 = 0.3758moles

Answer:
The mass of an object is 0.6122 Kg
Explanation:
Given:
Acceleration = 9.8 m/s
Force = 58.8 N
To Find:
Mass of an object = ?
Solution:
We know that according to newtons 2nd law
Force is the product of the mass and acceleration
F= ma
where
F = Force
m = mass
a = Acceleration
Substituting the values,
58.8 = m X 9.8
m = 0.6122 kg
