Answer:
solution:-a homogenous mixture of two or more substances in relative amounts that can be varied continuously up to what is called the limit of solubility.
solute:-is a substance, usually a solid, that is dissolved in a solution, which is usually a liquid.
solvent:-substance, ordinarily a liquid, in which other materials dissolve to form a solution.
polar molecule:-is a molecule in which one end of the molecule is slightly positive, while the other end is slightly negative.
Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out.
concentration refers to the amount of a substance in a defined space.
Explanation:
The primary components of rocks are minerals.
Look up a picture of the elements on a periodic table. Start reading from the top.
We can see here that the both measurements are accurate. This is the true because the both values are in the correct number of significant figures.
<h3>What is density?</h3>
The term density has to do with the ratio of the mass to the density of the object. We know that the accuracy of a measurement has a lot to do with the number of significant figures in the measurement. In this case, we are told that two students in a lab are asked to calculate the density of a block with a mass of 31.0 g; they are not told how many digits to round their measurements. Student A finds length to be 2 cm width to be 4 cm and height 8 cm. Student B finds the length to be 2.65 cm, width to be 4.20 cm, and height to be 8.35 cm.
For the first student, the density is obtained as;
Density = mass/ volume
= 31.0 g/ 2 cm * 4 cm * 8 cm
= 0.5 g/cm^3
For the second student;
Density = mass/ volume
= 31.0 g/2.65 cm * 4.20 cm * 8.35 cm
= 0.33 g/cm^3
