plz friends some one help me......
I want it with steps.....​

Answer 1

Answer:

3. molar mass= mole * atomic mass

=0.5*28

=14 gm

4.molar mass=0.5*14

=7 gm

5. mole =3.011*10^23/6.022*10^23

=0.5 mol

mass=0.5*28

=14gm

6. mole=6.022*10^23/6.022*10^23

=1 mol

mass=1*28

=28gm

7. mole=46/23=2mol

number of particles= 2*6*10^23=12*10^223

8. mole=8/32=0.25

no. of particles=0.25*6*10^23=1.5*10^23

9. no. of particles=0.1*6*10^23=0.6*10^23
