I need help with my homework.Calculate the number of formula units in: 41.5 grams CaBr2

lana66690 [7]

Answer:

$\text{ }1.25\times10^{23}\text{ formula units}$

Explanation:

Here, we want to calculate the number of formula units in the given molecule

We start by getting the number of moles

To get the number of moles, we have to divide the mass given by the molar mass

The molar mass is the mass per mole

The molar mass of calcium bromide is 200 g/mol

Thus, we have the number of moles as follows:

$\frac{41.5}{200}\text{ = 0.2075 mol}$

The number of formula units in a mole is:

$1\text{ mole = 6.02 }\times10^{22}\text{ formula units}$

The number of formula units in 0.2075 mole will be:

$0.2075\text{ }\times6.02\times10^{23}\text{ = }1.25\times10^{23}\text{ formula units}$

Which type of solar radiation is the most powerful?

QveST [7]

Gamma ray outbursts are an extremely dangerous sort of radiation.
Gamma rays have the most energy on the electromagnetic spectrum
They also have the shortest wave length.
If a gamma ray burst hit us, the rays would instantly destroy half of the ozone layer, stripping away our most important protective layer. This would cause mass extinction as the other uv rays from our sun would kill us

What did Helsenberg's Uncertainty Principle show about electrons?

DanielleElmas [232]

The Heisenberg Uncertainty Principle states that it is impossible to determine simultaneously both the position and the velocity of a particle. The detection of an electron, for example, would be made by way of its interaction with photons of light.
