Question

calculate the molecular marks of H20
​

Answer 1

Explanation:

H ydrogen molecular mass is 1

here h2 means,1+1=2

O is 16

16+2=18

Therefore molecular mass of h20=18

Answer 2

Answer:

heya mate there's your answer

The molecular mass of water(H2O)is 18

as Hydrogen mass is 1and there are 2 hydrogen then 1×2=2

And mass of Oxygen is 16

now add both values 2+16=18

hope it helps you

Thank you
