Answer 1

Answer:

12.01+32=44.01

=4/44.01

= 0.0908884344

0.090884344 mole

mole=molecule

Answer 2

Explanation:

mass = molecular weight / avagadro no

×number of molecules

4 = 12+(16×2)/6.022 ×10^23

×number of molecules

4 × 6.022 × 10^23 /44 = no of molecules

6.022×10^23/11 = no of molecules
