Question

plzz solve all if u can

Answer 1

1) Total no of electrons in p3- ion are

Atomic no + charge

= 15 + 3

= 18 electrons

2) 4.4g CO2

moles = 4.4/44 =0.1

No. of atoms = 0.1 × 6.022 × 10^23

= 6.022 × 10^22 atoms

3) Neutron in NH3

There are 7 neutron in NH3

4) Sugar is C12H22O11

1mole = 32.4/342 = 0.094

hydrogen atoms are

0.094 × 22 × 6.022 × 10^23

1.24 × 10^24 hydrogen atoms

5) Potash alum is KAl(SO4)2. 12H2O

39 + 27 + 2×32 + 8×16 + 24×1 + 12×16

474u
