The mass of the acetic acid is 1.512 g.
<h3 /><h3>What is Molarity?</h3>
molarity is the concentration of a substance in mol per dm³
From the question,
The number of moles contained in the 30 mL vinegar is
- n = (0.84×30)/1000
- n = 0.0252 mol.
the molar mass of vinegar is calculated below.
- m.m of (HC₂H₃O₂) = [1+(12×2)+(1×3)+(16×2)]
- m.m = (1+24+3+32]
- m.m = 60 g/mol.
To calculate the mass of acetic acid, we use the formula below.
- R.m = n×m.m............. Equation 1
Where
- R.m = mass of acetic acid.
Substitute these values into equation 1
- R.m = (0.0252×60)
- R.m = 1.512 g.
Hence, The mass of the acetic acid is 1.512 g.

Answer: They may be relocated for a job
There are many people in the United States that don’t tend to buy their own house and prefer to live on rent, the major reason that they do not buy their own house is because of the nature of their job. The job that they do, require a lot of moving around in the states which as a result demands for them to move frequently and in such cases many people avoid to buy a house because you cannot live in it for a long period of time.
There are different kinds of Heat Transfer. Conduction is the transfer of Thermal energy from one object to another through the movement of Molecules Heat flows from one molecule to another because the particles are in Direct contact with one another.
Conduction is known to be described as the transfer of heat between substances that are said to be in direct contact with each other.
The more the increase in the conductor, the more fast the heat will be transferred. Metal are known to be a good conduction of heat.
Conduction is known to often take place when a substance is heated and as such particles will have a lot of energy, and vibrate more.
