Question

what is the mass in grams of 5 moles water?

Answer 1

Heya!
--------

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

♦Given that =>
==========


⚫Number of Moles ( n ) => 5


⚫Molecular Mass of water < H2O > = 18


=> Number of Moles ( n ) = Given Mass / Molecular Mass


=> 5 = Given Mass / 18


=> Mass = 5 × 18


=> Mass = 90 g


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

Answer 2

Hey !!!

Solution: -

Given
mole of water = 5 mole
Molecular wt = 18

Since , we know that

mole = mass / molecular wt

5 mole = mass of H2O / molecular wt of H2O

5mole = mass of H2O/18

18 × 5 = mass of H2O

mass of water = 90g Answer ✔
