  • Mass=22.2cg=2.22g

Volume:-

\\ \tt\longmapsto 0.333(0.444)(0.555)=0.08cm^3

So

\\ \tt\longmapsto Density=\dfrac{Mass}{Volume}

\\ \tt\longmapsto Density=\dfrac{2.22}{0.08}=27.75g/cm^3

Zn-64 = 48.63%
Ann [662]

Answer:

A = 65.46 u

Explanation:

Given that,

The composition of zinc is as follows :

Zn-64 = 48.63%

Zn-66 = 27.90%

Zn-67 = 4.10%

Zn-68 = 18.75%

Zn-70 = .62%

We need to find the  average atomic mass of the given element. It can be solved as follows :

A=\dfrac{48.63\times 64+27.90\times 66+4.1\times 67+18.75\times 68+0.62\times 70}{100}\\A=65.46\ u

So, the average atomic mass of zinc is 65.46 u.

How many unpaired electrons are present in the ground state of an atom from each of the following groups?
Paha777 [63]

Explanation:

General electronic configuration for the given groups are as follows.

For 4A(14) : ns^{2}np^{4}

This means that there are 4 unpaired electrons in group 4A(14).

For 7A(17) : ns^{2}np^{5}

So, there are 7 unpaired electrons present in group 7A(17).

For 1A(1) : ns^{1}

Hence, there is only one unpaired electron present in group 1A(1).

For 6A(16) : ns^{2}np^{4}

So, there are 6 unpaired electrons present in group 6A(16).
