Question

what is the mass of 2.5 mole of water molecule​

Answer 1

Answer:

we know that 1 mole =6.022×10²³ molecules

mass of H2o(water)= 17

17 mass of water is =6.022×10²³

1 mass of water is =6.022×10²³

17

Therefore for 2.5 moles of water,

=→6.022×10²³ ×2.5

17

=→8.857×10²³

Answer 2

Given Mass / Molecular = Mole

_______________________

Mole => 2.5

Molecular mass => 1 × 2 + 16

Molecular mass => 18

Given Mass => X

_______________________

$\frac{x}{18} = 2.5 \\ x = 2.5 \times 18 \\ x = 45$

_______________________

Mass of 2.5 Mole of H2O => 45
