Concept explainers
(a)
Interpretation:
The molarity of sulfuric acid solution should be calculated.
Concept introduction:
The molarity of a solution is defined as number of moles of solute in 1 L of solution. It is mathematically represented as follows:
Here, n is number of moles of solute, V is volume of solution in L.
Number of moles can be calculated from mass and molar mass of a substance as follows:
Here, m is mass and M is molar mass.
(b)
Interpretation:
The time to fill a 55-gallon drum and the sulfuric acid contained in the drum should be calculated.
Concept introduction:
Time can be calculated from volume and flow rate as follows:
Here, V is volume of drum and
The mass of any substance can be calculated from its density as follows:
Here, m is mass, d is density and V is volume.
(c)
Interpretation:
Estimate the time it takes the solution to flow from the pipe inlet to the outlet.
Concept introduction:
The mean velocity of a pipe can be calculated from the following formula:
Here,
