Answer:
Lithium,Sodium,Potassium all belong to transition metals
1 mole ------------ 6.02 x10²³ molecules
? mole ----------- 1.505 x10²³ molecules
1.505x10²³ / 6.02x10²³ => 0.25 moles
hope this helps!
Answer:
The concentration of dilute solution is 0.72M
Explanation:
According to the given question
V1=30 ml
S1 = 12 M
V2= 500 ml
then S2 =?
we all know that V1S1=V2S2
or S2= V1S1÷V2
or S2 = 30×12÷500
or S2= 360÷500
or S2 =0.72 M.
The concentration of dilute solution is 0.72 M
