The morality of the solution that contains 5.0 moles of solute in 2 .0 liters in the solution is calculated as follows
molarity =moles/volume in liters
= 5 moles/ 2 l = 2.5M
Answer:
V CH3OH = 262.5 mL
Explanation:
- %v/v = (v compound / v sln)×100
∴ %v/v = 21.0 %
∴ v sln = 1.25 L
⇒ v compound = ?
⇒ 21.0 % = ( v compound / 1.25)×100
⇒ 0.21 = v compound / 1.25 L
⇒ (0.21)*(1.25 L) = v compound
⇒ v compound = 0.2625 L = 262.5 mL
Explanation:
Hey there!!
We generally use s,p,d,f formula.
So, let's do with it.
1.Neon
Atomic no. = 10
So, Its electronic configuration is;
2.Zinc.
Atomic no. = 30
So, it's electronic configuration is;
3. Tungsten.
Atomic no. = 74.
So, it's electronic configuration is;
4. Magnesium.
Atomic no. = 12
So, the electronic configuration is ;
