Answer:
bromine water
Explanation:
a simple test with bromine water can be used to tell the difference between an alkane and an alkene. an alkene will turn brown bromine water colourless as the bromine reacts with the carbon-carbon double bond.
The molarity of the solution is calculated by dividing the number of moles of the solute, in moles, by the total volume of the solution, in liters.
The molar mass of calcium hydroxide, Ca(OH)2 is calculated below.
m = molar mass Ca + 2(molar mass O) + 2(molar mass H)
Substituting,
m = 40 g/mol + 2(16 g/mol) + 2(1 g/mol)
m = 74 g/mol
To get the number of moles Ca(OH)2 in 75.8 grams,
n = (75.8 grams)(1 / 74 g/mol) = 1.024 moles
The molarity, M, is therefore,
M = (1.024 moles Ca(OH)2) / (1.2 L)
M = 0.854 M
<em>Answer: 0.854 M</em>
