Answer: habitat

Explanation:

A specie's habitat is the immediate environment suitable for the organism in which it lives and thrives. Each specie has specific adaptations which helps the organism to survive in its habitat. For instance, organisms that survive in arid regions have adaptive structures that minimizes water loss from the organism. The particular area inhabited by an organism within its habitat is the organism's ecological niche.

7.02 x 10^23 molecules of X2, a ssubstance consisting of diatomic molecules, has a mass of 296 grams. Determine the atomic weigh

Fiesta28 [93]

Answer:

d. 127 g/mol.

Explanation:

Hello!

In this case, since we have the amount of molecules of this this compound, we are able to compute the moles out there by using the Avogadro's number:

$mol=7.02x10^{23}molec*\frac{1mol}{6.022x10^{23}molec}=1.17mol$

Which correspond to the moles of X2. Then, by using the mass we are able to compute the molar mass of X2:

$MM=\frac{296g}{1.17mol}\\\\MM=254g/mol$

It means that the atomic mass of X halves the molar mass of X2, which is then d. 127 g/mol.

Best regards!
