Question

How many molecules of water of there in 54 g of h2o

Answer 1

Answer:

3 * 6.022*10^23 molecules

Explanation:

Molar weight of water is 18 g

So, 54 gram includes 3 moles

So, 3NA molecules=3*6.022*10^23

Answer 2

Answer:

hey mate here is ur ans❤☺️☺️

━━━━━━━━〢━━━━━━━━━━━━〢━━━━━━━━

molar mass=H20=1×2+16

=18

no. of moles =given mass / molar mass

=54/18

=3

no. of molecules =3×6.022×

${10}^{23}$

=1.8×1024
