Answer:
130.4 grams of sucrose, would be needed to dissolve in 500 g of water.
Explanation:
Colligative property of boiling point elevation:
ΔT = Kb . m . i
In this case, i = 1 (sucrose is non electrolytic)
ΔT = Kb . m
0.39°C = 0.512°C/m . m
0.39°C /0.512 m/°C = m
0.762 m (molality means that this moles, are in 1kg of solvent)
If in 1kg of solvent, we have 0.712 moles of sucrose, in 500 g, which is the half, we should have, the hallf of moles, 0.381 moles
Molar mass sucrose = 342.30 g/m
Molar mass . moles = mass
342.30 g/m . 0.381 m = 130.4 g
Most of the common inorganic polyatomic ions<span> have negative </span>charges<span>. This means the </span>ion has<span> more electrons than the neutral atoms that are in the </span>ion<span>. A </span>polyatomic ion<span> like phosphate, PO</span>43- has three<span> extra electrons beyond the electrons on the P and O atoms. Got this off google sorry if it doesn't help you :(</span>
