Question

An magnic acid of molecule mass 90.0, contains 26.66./. Carbon and 2.22./. Hydrogen calculate molecular formula of the acid

Answer 1

Answer:

Explanation:

carbon = 26.6/12

= 2.22

hydrogen = 2.22/2

=1.11

oxygen = 71.12/16

= 4.44

(C2 H 1 O4) n

= mass of (C2 H 1 O4)/ molecular mass

n= 90/90=1

molecular formula is (C2 H 1 O4)
