Answer:

The correct answer is - 11.209 moles.

Explanation:

According to the definition of moles,

moles = weight/molecular weight

given:

weight of beryllium = 101 g

the molecular weight of beryllium = 9.01

∵ 9.01 g weight of beryllium = 1 mole

∴ 1 g weight of beryllium = 1/9.01 moles

∴ 101 g of beryllium =101/9.01  moles

The = 11.209 moles.

Explain the main cause of degradation of our languages in belize? it's science but I put biology​
Nonamiya [84]

Language degradation is occurring because of the adoption of foreign languages.

<h3>How does this adoption take place?</h3>

The constant presence of foreign media and the adoption of foreign language terms is the main way to adopt a new language.

This adoption allows the local population to start mixing the two languages.

Over time this process becomes more intense, causing the local language to be replaced by a foreign language over time.

Language degradation is a process that occurs in many regions, but maintaining these languages is very important.
