Calculate each of the following quantities:<br> (a) Total number of ions in 38.1 g of SrF₂
adelina 88 [10]

The total number of ions in 38.1 g of SrF₂ is 5.479 x 10²³.

<h3>What are ions?</h3>

Ions are the elements with a charge on them. It happens when they share electrons with other atoms to form a compound.

We have to calculate the total number of ions in 38.1 g of .

The molar mass of SrF₂ = 125.62 g/mol

The number of moles = 38.1 g of  1.0 mol / 125.62  = 0.30329 moles

Given that, total moles of SrF₂ ions in  = 1.0 mol of + 2.0 moles of  = 3.0 moles

Total moles of ions in 0.30329 moles of

= (0.30329 moles of SrF₂) x 3.0 / 1.0  = 0.90988 mol ions

We know that,

1.0 mole of ions = 6.023 x 10²³ ions

Thus, the number of total ions = ( 0.90988 mol ions) x  6.023 x 10²³ / 1.0 mol = 5.479 x 10²³ ions

Thus, the number of ions is in 38.1 g of 5.479 x 10²³ ions

Suppose a scientist proposes a plan to destroy all bacteria on Earth in order to get rid of diseases caused by bacteria. Explain
dimulka [17.4K]
This would not be a good idea because bacteria is everywhere and function as a part of out everyday lives. Starting off with animals, many animals rely on bacteria to digest their food so many animals would begin to die off. Ecosystems would fail due to nitrogen not being able to cycle.
Without bacteria biological waste would build up causing a drop in population, eventually going extinct.
Basically, the balance of nature between humans, animals, and plants would no longer exist.
