For example: The height of the building is 150 meters. This statement means that the length of the building from the ground is 150 and it is measured in the units of meters.
Hence, the given quantity is a type of length and is measured i the units of meters.
Answer:
Molar mass of acetic acid is 60 g/mol
Explanation:
Look at the formula:
CH₃COOH
We have:
- 2 moles of C → 12.011 amu . 2 = 24 g/mol
- 4 moles of H → 1.008 amu . 4 = 4 g/mol
- 2 moles of O → 15.999 amu . 2 = 32 g/mol
Let's sum the mass of each element
24 g/mol + 4 g/mol + 32 g/mol = 60 g/mol
Answer:
You need to heat the mixture to 78.37°C
Explanation:
In distillation, you can separate 2 or more compounds based on their difference in boiling points.
In a mixture of ethanol and water, in theory, you need to heat the mixture to 78.37°C. In this temperature, the ethanol must be evaporated and then condensed in the receiving flask.
