Answer:

The desert should be divided into different types based on its properties. The organisms living in specific type of desert should be named accordingly.

Explanation:

There are usually five major types of desert in the world. Tropical, rainy, semi arid desert, coastal desert and dry desert. There are many different types of organisms living in these deserts. The biodiversity has made it difficult for the humans to analyse and identify the millions of different types. The best way is to organize and name the organisms that live in specific types of deserts.

when 1.570 grams of the compound is vaporizedar 300 degrees celius and 1 atmosphere, the gas occupies a volume of 577 milliliter
Archy [21]

Answer:

128 g/mol

Explanation:

The molar mass is how much a mol of the substance weight.

In this question the weight is given (1.570 g).

To find the number of moles in the sample, we use the ideal gas law: PV=RnT

P= 1atm

V= 577mL= 0.577L

R (universal gas constant)= 0.08206(\frac{atm*L}{mol*K})

n= number of moles

T= 300°C= 573.15K

Solving for n:

n= \frac{1 atm*0.577L}{0.08206\frac{atm*L}{mol*K}*573.15} <em>k</em>

n=0.0123mol

Molar mass=\frac{1.570g}{0.0123 mol}

Molar mass=128\frac{g}{mol}

You have 0.21 moles of Al how many atoms do you have
ZanzabumX [31]

Number of atoms : 1.26 x 10²³

<h3>Further explanation  </h3>

The mole is the number of particles(molecules, atoms, ions) contained in a substance  

1 mol = 6.02.10²³ particles

Can be formulated

N=n x No

N = number of particles

n = mol

No = Avogadro's = 6.02.10²³

0.21 moles of Al, so n = 0.21

Number of atoms :

\tt N=0.21\times 6.02\times 10^{23}\\\\N=1.26\times 10^{23}
