Question

How many molecules of HCI would react with 2 moles of AI?

2AI + 6HCI -> 2AICI3+3H2

A. 1.806x10^23
B 1.806x10^24
C 2.007x10^23
D 6.02x10^23

Answer 1

B. 1.806 x10^24

Step-by-step explanation:

:p

Answer 2

1.806 x10^24

Step-by-step explanation:

as 2 moles of Al are reacting with 6 moles of HCl that means For the reaction of 1 mole of Aluminium needs 3 moles of HCl

Formula for No of molecules is,

No of Molecules = Moles x Avogadro's No

= 3 x (6.02 x10^23)

= 1.806 x10^24
