12. The vapor pressure of water at 90°C is 0.692 atm. What is the vapor pressure (in atm) of a solution made by dissolving 3.68
luda_lava [24]

Answer : The vapor pressure (in atm) of a solution is, 0.679 atm

Explanation : Given,

Mass of H_2O = 1.00 kg = 1000 g

Moles of CsF = 3.68 mole

Molar mass of H_2O = 18 g/mole

Vapor pressure of water = 0.692 atm

First we have to calculate the moles of H_2O.

\text{Moles of }H_2O=\frac{\text{Mass of }H_2O}{\text{Molar mass of }H_2O}=\frac{1000g}{18g/mole}=55.55mole

Now we have to calculate the mole fraction of H_2O

\text{Mole fraction of }H_2O=\frac{\text{Moles of }H_2O}{\text{Moles of }H_2O+\text{Moles of }CsF}=\frac{55.55}{55.55+3.68}=0.938

Now we have to partial pressure of solution.

According to the Raoult's law,

P_{Solution}=X_{H_2O}\times P^o_{H_2O}

where,

P_{Solution} = vapor pressure of solution

P^o_{H_2O} = vapor pressure of water = 0.692 atm

X_{H_2O} = mole fraction of water = 0.938

P_{Solution}=X_{H_2O}\times P^o_{H_2O}

P_{Solution}=0.938\times 0.692atm

P_{Solution}=0.649atm

Therefore, the vapor pressure (in atm) of a solution is, 0.679 atm

-Dominant- [34]

Answer:

15 ml

Explanation:

\frac{40,5}{y}=\frac{2,7}{1}

2,7y=40,5

y=40,5/2,7=405/27= 15ml

Which statement accurately describes the evidence that scientists gather using fossils? Check all that apply.
OLga [1]

Complete question is;

Which statements accurately describe the evidence that scientists gather using fossils? Check all that apply.

A) The fossil record can be used to date rocks.

B) Living things with many cells have always lived on Earth.

C) Simple organisms are found only in young rocks.

D) Geologists study ancient remains of plants and animals.

E) Scientists can figure out what ancient living things ate.

F) Pollen and seeds help provide clues about ancient climates.

Answer:

A) The fossil record can be used to date rocks

E) Scientists can figure out what ancient living things ate.

F) Pollen and seeds help provide clues about ancient climates

Explanation:

In scientific research, fossils are sometimes referred to as animals and plant. Now, in studying records of fossils, it will be easy to know the length of existence of living things on the Earth. Also, we can be able to identify the manner in which different relationships exists between plants and animals by predicting their lifestyles, location of their habitation e.t.c which can be used to predict the old time climates.

Looking at the options given in relation to the explanation given, options A, E & F are correct
