Answer: Yes

Explanation:

With more water, the molecules of the substance have more water molecules to form bonds with, thus they are dissolved even faster at that same particular temperature.

For example: a mildly soluble substance like powdered milk get more dissolved in your teacup as water, the solvent is increased

How does the eruption of a volcano lower the atmospheric temperature?

lianna [129]

The eruption of a volcano lowers the temperature in the environment. The first time this observation was made, it was noticed that winter came aryl that year and the first snow that fell did not immediately melt on the ground. The ash and smoke from the eruption of volcanoes creates a cloud and shroud which dims the effect of the sun and the land gets less exposure to strong sunlight. This in turn results in the lowering of temperature.

A 10.0 L flask at 318 K contains a mixture of Ar and CH4 with a total pressure of 1.040 atm. If the mole fraction of Ar is 0.715

andrey2020 [161]

Answer:

$w_{Ar}=0.814$

Explanation:

Hello,

In this case, given the temperature, volume and total pressure, we can compute the total moles by using the ideal gas equation:

$PV=nRT\\\\n=\frac{PV}{RT}=\frac{1.040atm*10.0L}{0.082\frac{atm*L}{mol*K}*318K}\\ \\n=0.41mol$

Next, using the molar fraction of argon, we compute the moles of argon:

$n_{Ar}=0.41mol*0.715=0.29mol$

And the moles of methane:

$n_{CH_4}=0.41mol-0.29mol=0.12mol$

Now, by using the molar masses of both argon and methane, we can compute the mass percent of argon:

$w_{Ar}=\frac{m_{Ar}}{m_{Ar}+m_{CH_4}}=\frac{0.29mol*\frac{40g}{1mol} }{0.29mol*\frac{40g}{1mol}+0.12mol*\frac{16g}{1mol}} \\\\w_{Ar}=0.814$

Regards.

How many moles is in 2.52*10^24 molecules of water?

nataly862011 [7]

Hi friend
--------------
Your answer
-------------------

Water = H2O

Number of molecules in one mole of water = 6.022 × 10²³ [Avogadro's constant]

Given number of molecules = 2.52 × 10²³

So,
------

Number of moles =
$\frac{2.52 \times 10 {}^{24} }{6.022 \times 10 {}^{23} } \\ \\ = 4.184 \: (approximately)$
