Question

what is the moles 0.5 water​

Answer 1

Answer:

Given Data:

Mass of Water = ?

no. of moles = 0.5

Molar mass of H₂O = 2(1) + 16 = 18 g/mol

Formula to be Used:

No. of moles = Given Mass/Molar mass

Solution:

No. of moles = Mass of Water/Molar mass

0.5 = Mass of Water/18

Mass of Water = 0.5*18

Mass of Water = 9g

Result:

The mass of 0.5 mole of water is 9g.

Answer 2

Answer:

9g 10

Explanation:

: 0.2 moles of oxygen atoms = 16

= 16×0.2 = 3.2(g)

(b) 1 mole of water molecules = 18g

0.5 moles of water molecules = 18×0.5

= 9g10
