Answer 1

18.01528 9/mol

hope dis helps ^_^

Answer 2

====================================

$\huge{\bold{\boxed{\red{HELLO!!}}}}}$

$\huge{\bold{\underline{\mathfrac{\maroon{UrAnswer!}}}}}}$

Molecular Formula of water is H₂O

So molecular mass = atomic mass of 2 hydrogen+ atomic mass of one oxygen

$\huge{\bold{\green{= 2*1 + 16}}}}}$

$\huge{\bold{\green{=2+16}}}}}$

$\huge{\bold{\green{=18}}}}}$

$\huge{\bold{\boxed{\red{plzNote!!}}}}}$

Atomic mass of one hydrogen=1

Atomic mass of one oxygen=16
