How many moles are in 4.01x10^24 particles?
skelet666 [1.2K]

Answer:

6.64

Explanation:

so moles

\frac{number  \: of \: \: particles \: }{6.02 \times  {10}^{23} }

then do =4.01×10^24/6.02×10^23

you get the answer as 6.6445 u only need to write the answer to

3.S.F 6.64 moles

hope this make sense :)

A solution of methanol and water has a mole fraction of water of 0.312 and a total vapor pressure of 211 torr at 39.9∘C. The vap
DaniilM [7]

Answer : This is not an ideal mixture.

Explanation :

Using Raoult's law :

P_{Mixture}=p_{CH_3OH}+p_{H_2O}\\\\P_{Mixture}=x_{CH_3OH}\times p^o_{CH_3OH}+x_{H_2O}\times p^o_{H_2O}

where,

P_{Mixture} = total vapor pressure of mixture

p^o_{CH_3OH} = vapor pressure of pure methanol = 256 torr

p^o_{H_2O} = vapor pressure of pure water = 55.3 torr

x_{H_2O} = mole fraction of water = 0.312  

x_{CH_3OH} = mole fraction of methanol = 1 - 0.312 = 0.688

Now put all the given values in the above formula, we get:

P_{Mixture}=x_{CH_3OH}\times p^o_{CH_3OH}+x_{H_2O}\times p^o_{H_2O}

P_{Mixture}=0.688\times 256torr+0.312\times 55.3torr

P_{Mixture}=193.4torr

From this we conclude that the total vapor pressure of mixture is less than the total given vapor pressure of 211 torr. That means, the interactions between the methanol and water would be weaker than those between the individual substances. So, this is not an ideal mixture.

Hence, this is not an ideal mixture.

Do we lose taste buds as we age?
Doss [256]
Between the ages of 40 and 50, the number of taste buds decreases, and the rest begin to shrink,losing mass vital to their operation.  After age 60, you may begin to lose the ability to distinguish the taste of sweet, salty, sour, and bitter foods.
