32. A solution suspected of containing copper is analyzed. To recognize the standard curve, the absorbance of five criteria ran

nlinux.org:

0.689 mg/L Cu

Explanation:

The equation of the best-fit line is:

y = 0.6136x + 0.0142

Where y is the absorbance and also x is the concentration in mg/L.

Now using that equation we calculate x when y is equal to 0.438, 0.434 & 0.439.

1) 0.438 = 0.6136x + 0.0142

x = 0.691 mg/L

2) 0.434 = 0.6136x + 0.0142

x = 0.684 mg/L

3) 0.439 = 0.6136x + 0.0142

x = 0.692 mg/L

Finally we calculate the mean of the 3 concentrations:

(0.691 + 0.684 + 0.692)/3 = 0.689 mg/L

An aqueous solution of sulfuric acid has actually a composition of 25wt% and a SG of 1.22. Calculate the Volume of the solution that has

nlinux.org: The volume of solution is

*

Explanation:

The connection between specific gravity and thickness of a substance is given as:

*

Specific gravity of sulfuric acid solution = 1.22

Density of water = 1.00 g/mL

Putting worths in over equation we get:

*

We are given:

25% (m/m) sulfuric acid solution. This suggests that 25 g of sulfuric acid is present in 100 g of solution

Convariation factor: 1 kg = 1000 g

Mass of solution having actually 254 kg or 245000 g of sulfuric acid is calculated by making use of unitary method:

If 25 grams of sulfuric acid is current in 100 g of solution.

So, 245000 grams of sulfuric acid will be existing in =

*

To calculate volume of a substance, we use the equation:

*

Density of solution = 1.22 g/mL

Mass of Equipment = 980000 g

Putting values in over equation, we get:

*

Hence, the volume of solution is

*
