5) Calculate the volume, in liters, of 3.24 x 1022 molecules<br> CI2

azamat

Answer: 1.12 Liters

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number $6.023\times 10^{23}$ of particles.

To calculate the moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given molecules}}{\text {avogadro's number}}=\frac{3.24\times 10^{22}}{6.023\times 10^{23}}=0.05moles$

1 mol of $Cl_2$ occupy = 22.4 L

Thus 0.05 mol of $Cl_2$ will occupy = $\frac{22.4}{1}\times 0.05=1.12 L$

Need help on this question asap please

3241004551 [841]

Answer:

The correct answer is - 14.

Explanation:

In the given molecular formula of the aluminum sulphite which is Al2(SO3)3, this molecular formula there different type of elements are bonded together to form this compound each element has a specific number of atoms present. This compound has three elements that are aluminum, sulfur, and oxygen and the atoms are present are:

Al = 2 atoms represented by subscript

S = 3 atoms represented as whole subscripts of sulfite

O = 9 atoms 3 inside bracket and 3 outside of bracket that multiplies.

Thus, total number of atoms are 2+3+9 = 14

Please help thaank youu

First, let's start off by finding the mass of this whole hydrate.
(Note: the unit of measurement for mass will be amu)

Let's find the molecular mass of each element.
$Co=58.933$
$Cl=35.45$
$H=1.008$
$O=15.999$

Now, let's find the mass of each compound.

$CoCl_2=58.933+2(35.45)=129.833$
$H_2O=2(1.008)+15.999=18.015$

We have 6 molecules of H2O, so multiply 18.015 by 6 then add that with the weight of CoCl2.

$6(18.015)=108.09$
$129.833+108.09=237.923$

Now divide 108.09 (mass of all the H2O in the hydrate) by 237.923 (total mass of hydrate).

$\dfrac{108.09}{237.923}$

$\approx0.45431$

Turn that into a percentage and you get 45.431%.
Hope this helps! :)

The fluid in a barometer (shown above) is mercury, Hg. Why point

PIT_PIT [208]

Answer:

Mercury responds to temperatures differently than water. When mercury is cold, the molecules bunch together, making it seem to be less liquid, and the opposite happens during heat.

Hope this helps!
