Answer:
3.6mol Li
Explanation:
To get the amount of moles from the mass we divide the mass by the molar mass.
25g ÷ 6.941g/mol = 3.6mol Li
Answer:
2.5l
Explanation:
They higher the temprature the higher the volume
Answer:
106.6 °C
Step-by-step explanation:
The formula for <em>boiling point elevation</em> ΔTb is
ΔTb = iKb·b
where
i = the van't Hoff i# factor
Kb = the molal boiling point elevation constant
b = the molal concentration of the solution
=====
<em>Data
</em>
i = 2, because 1 mol of NaCl gives 2 mol of ions in solution.
Kb = 0.51 °C·mol·kg⁻¹
b = 1.00/0.155
b = 6.452 mol·kg⁻¹
=====
<em>Calculations
</em>
ΔTb = 2 × 0.51 × 6.452
ΔTb = 6.58°C
Tb = Tb° + ΔTb
Tb = 100 + 6.58
Tb = 106.6 °C
