Given : Density of Bromine = 3.12 g/mL
Formula : Density = Mass / Volume

Part A :
Given Volume = 125 mL
Density = Mass / Volume
So, Mass = Density x Volume
= 3.12 x 125
= 390 grams

Part B :
Given mass = 85.0 gm
Density = Mass / Volume
So, Volume = Mass / Density
= 85 / 3.12
= 27.24 mL

1.a)concentrated sulphuric acid reacts with ethanol to produce ethene

Murljashka [212]

Answer: a) Temperature of $170^0C$

b) $C_2H_5OH\stackrel{conc H_2SO_4, 170^0C}\rightarrow C_2H_4+H_2O$

c) dehydrating agent

Explanation:

Ethanol is heated with an excess of concentrated sulfuric acid at a temperature of 170°C to produce ethene.

The balanced chemical reaction is:

$C_2H_5OH\stackrel{conc H_2SO_4, 170^0C}\rightarrow C_2H_4+H_2O$

Here concentrated sulfuric acid removes a water molecule from ethanol and thus acts as a dehydrating agent.
