The concept that can be used in order to determine the answer to this item is that of ratio and proportion. The ratio of the mass of the product to the sulfuric acid solution used in the first set should be proportional to that of the second. If we let x be the volume of the acid then, the equation that can be used is,
3.2 g / 4 L = 8 g / x L
The value of x from the equation is 10.
<em>ANSWER: 10 L</em>
Answer:
Particle density is the volumetric mass of the solid soil. It differs from bulk density because the volume used does not include pore spaces. Particle density represents the average density of all the minerals composing the soil.
Hope that helps

If the potassium atoms could be lined up in a row, it would take to make a 1.00 ft row of potassium atoms is 5.45 × 10⁻⁸.
Potassium atom is represented by K with atomic number 19. It is a silvery white metal.
Given,
Radius = 280pm = 280 × 10⁻¹²m
Diameter = 2radius = 560× 10⁻¹²m = 560pm
We know that,
1 feet = 0.305m
So, number of potassium atoms that fits into the row,
1 feet = 0.305/560 × 10⁻¹²
1 feet = 5.45 × 10⁻⁸
Hence, it takes 5.45 × 10⁻⁸ atoms of potassium to make a 1 feet row.
