What is the mass , in grams of 0.0287 moles of sucrose

Chemistry
1 answer:
VladimirAG [237]3 years ago
4 0

Hey there!

Sucrose is C₁₂H₂₂O₁₁.

Find molar mass of sucrose:

C: 12 x 12.01 = 144.12

H: 22 x 1.008 = 22.176

O: 16 x 11 = 176

--------------------------------

                  342.296 grams

That is the mass of one mole of sucrose.

We have 0.0287.

342.296 x 0.0287 = 9.82

The mass of 0.0287 moles of sucrose is 9.82 grams.

Hope this helps!

What is an aqueous solution? What is an aqueous solution? An aqueous solution is a homogeneous mixture of a substance with water
mestny [16]

Answer:

The answer to your question is: first option.

Explanation:

What is an aqueous solution?

Aqueous solution is a solution which solvent is water and is homogeneous.

a) An aqueous solution is a homogeneous mixture of a substance with water.  This is the correct definition of aqueous solution because it mentions the characteristics of this kind of solutions.

b) An aqueous solution is a dispersoid solution. This option is wrong, it is a homogeneous solution, and the description do not mention water.

c) An aqueous solution is a mixture of a liquid substances. Aqueous solution is a mixture but one of the components is water not a liquid substance.

d) An aqueous solution is a heterogeneous mixture of a substance with water. Aqueous solution is homogeneous not heterogeneous, this option is wrong.

_____ arises when you view a more or less uniformly patterned surface because the size of the pattern elements, as well as the d
ss7ja [257]

Answer:

Texture Gradient

Explanation:

Texture Gradient  -

It refers to the disrupted pattern on any uniform surface , is referred to as the texture gradient  .

The pattern is somewhat very uniform in nature , i.e. , is constant over a particular area .

The three types of texture gradient are-

  • perspective ,
  • density and
  • distortion of texture elements .

Hence , from the given information of the question ,

The correct answer is texture gradient .

A gas occupies the volume of 215ml at 15C and 86.4kPa?
kherson [118]

Answer:

About 0.1738 liters

Explanation:

Using the formula PV=nRT, where p represents pressure in atmospheres, v represents volume in liters, n represents the number of moles of ideal gas, R represents the ideal gas constant, and T represents the temperature in kelvin, you can solve this problem. But first, you need to convert to the proper units. 215ml=0.215L, 86.4kPa is about 0.8527 atmospheres, and 15C is 288K. Plugging this into the equation, you get:

0.8527\cdot 0.215=n \cdot 0.0821 \cdot 288\\n\approx 7.754 \cdot 10^{-3}

Now that you know the number of moles of gas, you can plug back into the equation with STP conditions:

1V=7.754 \cdot 10^{-3} \cdot 0.0821 \cdot 273\\V\approx 0.1738L

Hope this helps!

If I initially have a gas at a pressure of 12 atm, volume of 23 liters, and temperature of 200 K, and then I raise the pressure
CaHeK987 [17]

Answer : The volume of gas will be 29.6 L

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1 = initial pressure of gas = 12 atm

P_2 = final pressure of gas = 14 atm

V_1 = initial volume of gas = 23 L

V_2 = final volume of gas = ?

T_1 = initial temperature of gas = 200K

T_2 = final temperature of gas = 300K

Now put all the given values in the above equation, we get the final pressure of gas.

\frac{12atm\times 23L}{200K}=\frac{14\times V_2}{300K}

V_2=29.6L

Therefore, the new volume of gas will be 29.6 L
