Question

calculate the molecular mass of the following: a. H\/2O b.HCl c. H2S

Answer 1

Heya user !!!

Here's the answer you are looking for

The mass of H is 1g, O is 16g, Cl is 35.5g and S is 32g.

(a) H2O

2 × H + O

= 2(1) + 16

=2 + 16

= 18g

(b) HCl

= H + Cl

= 1 + 35.5

= 36.5g

(c) H2S

= 2 × H + S

= 2 (1) + 32

= 2 + 32

= 34g

Answer 2

Hey there,

Mass of the compound are as follows-

a-  H₂O
2(1)+(16)
=18

========================

b-  HCl
(1)+(35.5)
=36.4

===================

c-  H₂S
=2(1)+32
=2+32
=34
