Question

A 20.0-ml sample of glucose Iv solution has a mass of 20.6g.what is the density of the glucose​

Answer 1

Taking into account the definition of density, the density of the glucose is 1.03 $\frac{g}{mL}$.

What is density

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance. Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

$density=\frac{mass}{volume}$

From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.

Density of the glucose

In this case, you know that:

• Density= ?
• Mass= 20.6 g
• Volume= 20 mL

Replacing in the definition of density:

$density=\frac{20.6 g}{20 mL}$

Solving:

density= 1.03 $\frac{g}{mL}$

In summary, the density of the glucose is 1.03 $\frac{g}{mL}$.
