A 20.0-ml sample of glucose Iv solution has a mass of 20.6g.what is the density of the glucose​
xxTIMURxx [149]

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

<h3>What is density</h3>

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.

<h3>Density of the glucose</h3>

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:

<u><em>density= 1.03 </em></u>\frac{g}{mL}

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

Explain the various modes of dispersal of seeds and fruits.​
11Alexandr11 [23.1K]
There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus. Dispersal involves the letting go or detachment of a diaspore from the main parent plant.

Fruits and seeds dispersal is the process whereby fruits and seeds are scattered from their origin. The various ways by which fruit and seed are dispersed are known as agents of seed and fruit dispersal.
