<u>We are given: </u>
Mass of water: 119 grams
We know that one mole of a gas occupies 22.4L of volume
<u>Number of moles of water:</u>
Number of moles = given mass / Molar mass
Number of moles = 119 / 18 [molar mass of water = 18 grams/mol]
Number of moles = 6.61 moles
<u>Volume occupied: </u>
Volume = number of moles * 22.4 L
Volume = 6.61 * 22.4
Volume = 148L
Volume (in mL) = 1.48 * 10⁻¹ mL
As 1 L = 1000 g
so 119 grams = 0.119000 L
