calculate the mass of given substances (A) 4 mole of H²O (b)1.2 mole of CH³OOH​

Answer 1

Explanation:

answer of a is

1 mole of h20 weight is=approx 18

so

1 mole of h20=18

4 mole =x

cross multiply

we get 18×4=72

answer of b

is

1 mole of ch3cooh weight is approx 60

so

1 mole =60

1.2=y

after cross multiply we get
