The density of a solution of sulfuric acid is 1.29 g/cm3 and it is 38.1% acid by mass. What volume of the sulfuric acid solution
pychu [463]

Answer : The correct option is, (7) 332 mL

Explanation : Given,

Density of solution of sulfuric acid = 1.29g/cm^3=1.29g/mL

38.1 % acid by mass that means 38.1 grams of sulfuric acid present in 100 grams of solution of sulfuric acid.

Now we have to calculate the mass of solution of sulfuric acid.

As, 38.1 grams of sulfuric acid present in 100 grams of solution of sulfuric acid

So, 163 grams of sulfuric acid present in \frac{163}{38.1}\times 100=428.95 grams of solution of sulfuric acid

Now we have to calculate the volume of sulfuric acid solution.

Density=\frac{Mass}{Volume}

1.29g/mL=\frac{428.95g}{Volume}

Volume=332mL

Therefore, the volume of sulfuric acid solution needed is 332 mL.

7. Which particle diagram represents a mixture of three substances?"<br> Which option?
kozerog [31]

The particle diagram that represents a mixture of three substances is seen in Option 2.

A particle is a small portion of a matter that has both physical and chemical properties.

In inorganic chemistry, a substance refers to a form of matter ( usually particles) that can not be separated by ordinary physical means but by a chemical process.

It can either be:

  • an element or a compound.

From the information given, we have:

  • an atom of one element
  • an atom of a different element

Option 1, 3, and 4 show a particle diagram representing a mixture of only two substances but Only Option 2 shows a particle diagram representing a mixture of three substances.

Therefore, we can conclude that the particle diagram that represents a mixture of three substances is seen in Option 2.
