A sample of nitrogen gas has the temperature drop from 250.°c to 150.°c at constant pressure. what is the final volume if the in
Leviafan [203]
Charles law gives the relationship between temperature of gas and volume of gas.
It states that for a fixed amount of gas, temperature is directly proportional to volume of gas.
V / T = k
where   V- volume , T - temperature and k - constant 
\frac{V1}{T1} =  \frac{V2}{T2}
parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation.
T1 = 250 °C + 273 = 523 K
T2 = 150 °C + 273 = 423 K
Substituting the values in the equation,

\frac{310 mL}{523 K} =  \frac{V}{423K}
V = 251 mL
the new volume is 251 mL

when 1.00 l 1.00 l of a 0.500 m l i b r 0.500 m libr solution is tripled by dilution with water, what is the number of moles of
Murrr4er [49]

When 1.00 L of a 0.500 M LiBr solution is tripled by dilution with water . the number of moles of  lithium in new solution is 0.5 moles.

given that :

volume = 1.00 L

molarity = 0.500 M

The solution is tripled by dilution but there will be no effect in number of mole by the dilution.

the number of moles = molarity × volume in L

the number of moles = 1 × 0.500

the number of moles = 0.5 mol

Thus, When 1.00 L of a 0.500 M LiBr solution is tripled by dilution with water . the number of moles of  lithium in new solution is 0.5 moles.

The structure that corresponds to methylpropylether is the structure CH3 - O - C3H7 in option C.

<h3>What is structure?</h3>

The structure of a compound is defined as the way in which the atoms in the compound are arranged. We know that a compound is composed of atoms and these atoms are arranged in particular patterns in space. This is the stereochemistry of the molecule.

Now we know that methylpropylether is a compound that contains the methyl group and the propyl group separated by a oxygen atom as is typical of all ethers.

As such, the structure that corresponds to methylpropylether is the structure CH3 - O - C3H7 in option C.
