Answer:
Molarity = 1 mol.L⁻¹
Solution:
Molar concentration (Molarity) is given as,
Molarity = Moles / Volume of Solution ------ (1)
Data Given;
Moles = 4 mol
Volume = 4 L
Putting Data in Eq. 1,
Molarity = 4 mol ÷ 4 L
Molarity = 1 mol.L⁻¹
The metals are elements which have low ionization potential and can lose electrons easily
the other physical characteristics associated with them and hence with Aluminium are
a) they can conduct electricity in molten state, hence It would only conduct electricity if it were melted.
b) It could be stretched into a thin wire. It means it is ductile.
In case of given aluminium metal the correct answer is
it could be stretched to thin wire

</span>First order
in A and zero order in B
<span>ln [A]
= (ln 0.1) (2) + ln Ao = ln 0.01 + ln Ao = ln 0.01 Ao = 1.0% of A will remain</span>
<span>b)

<span>1/[A] – 1/[A]0= kt where t+=1 and k=9</span>
[A]/[A]=1/19=0.053=5.3%
