A student who is performing this experiment pours an 8.50 mL sample of the saturated borax solution into a 10 mL graduated cylin
belka [17]

Answer:

Ksp = 0.1762

Explanation:

Applying

a) moles of HCl added, n= CV=0.5×0.012 = 6×10-3mol

b) since 0.006mol is present in 0.012dm3 of HCl

It implies moles of borax

C) Concentration = 0.706M

Ksp = [0.5]^2[0.706]= 0.176

If 50.0 grams of HCl were dissolved in enough water to make a solution with a total volume of 5.0 liters, what would be the mola
SVETLANKA909090 [29]

The molarity of a solution is found to be 10 M.

Explanation:

  • Molarity of a solution = <u>moles solute</u>

                                        Litres solution

  • Therefore,M =<u> 50</u>

                        5

  • Molarity of a solution  = 10 M

7. A square chunk of plastic has a length of 5 cm, width of 5 cm and height of 5 cm. It has a mass of 200 g. What is its density
BaLLatris [955]

Answer:

d=1.6\ g/cm^3

Explanation:

Given that,

The dimension of a square chunk of plastic is 5 cm × 5 cm × 5 cm

Mass, m = 200 g

We need to find its density

Density = mass/volume

It will form a cube. It volume = side³

So,

d=\dfrac{200\ g}{5^3\ cm^3}\\\\d=1.6\ g/cm^3

Hence density is 1.6\ g/cm^3
