Answer:
0.22
Explanation:
Given, Mass of 
= 46.85 g
Molar mass of = 299.4 g/mol
The formula for the calculation of moles is shown below:
Thus,
Given, Mass of 
= 125.5 g
Molar mass of = 46.07 g/mol
The formula for the calculation of moles is shown below:
Thus,
So, according to definition of mole fraction:
First, we will need to find the density of the object, take the mass and divide it by the dispplaced water:
128/424 = 0.302 grams/milliliters
Convert that to kg/m3
We get: 302kg/m3
Divide that to the density of water: 1000kg/m3
302/1000 = 0.302
(thats a pretty darn light weighted metal)
