Answer: D) 2.38*10^-^2^2 g

Explanation: The question asks to convert formula unit to grams. It is a unit conversion problem.

1 mole equals to Avogadro number of formula units. So, to convert the given number of formula units to moles, we need to divide by the Avogadro number. After this, we do moles to grams conversion and for this the moles are multiplied by the molar mass of the compound. Molar mass of AgCl is 143.32 gram per mol.

1FormulaUnitAgCl(\frac{1mol}{6.022*10^2^3formulaUnits})(\frac{143.32g}{1mol})

= 2.38*10^-^2^2 g

So, the correct option is D) 2.38*10^-^2^2 g

Answer : The mass in grams of a single formula unit of silver chloride will be 2.38\times 10^{-22}g

Explanation:

Formula units : It is defined as lowest whole number ratio of ions in an ionic compound. It is calculate by multiplying the number of moles by Avogadro's number which is 6.022\times 10^{23}.

Single formula unit of silver chloride means that 1 mole of silver chloride.

We are given :

Number of moles of silver chloride = 1 moles

The molar mass of silver chloride = 143.32 g/mole

That means, 1 mole silver chloride contains 143.32 grams of silver chloride.

Now we have to determine the mass in grams of a single formula unit of silver chloride.

As, 6.022\times 10^{23} formula unit has mass = 143.32 g

So, 1 formula unit has mass = \frac{1}{6.022\times 10^{23}}\times 143.32=2.38\times 10^{-22}g

Therefore, the mass in grams of a single formula unit of silver chloride will be 2.38\times 10^{-22}g

What is soil? where do the water and nutrients found in the soil come from?
Liono4ka [1.6K]

Answer:

Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life.

We get these from the plants that grow, and the animals that we eat that eat the plants. Most soils have a large supply of nutrients in them, and they get taken up by plants when plants absorb water. Soils need to be healthy to grow large quantities of plants, and animals need plants to grow strong.
