a drop of gasoline has a mass of 22 mg and a density of 0.754 g/cm^3. What is its volume in cubic centimeters?
Verizon [17]
The density can be calculated using the following rule:
density = mass/volume
therefore,
volume = mass/density

we have the mass=22 mg=0.022 grams and density=0.754g/cm^3

substituting in the above equation, we can calculate the volume as follows:
volume = 0.022/0.754 = 0.0291 cm^3

What bond vibrations and stretching frequencies should you observe in the IR spectrum of caffeine?
Margarita [4]
  • The bond vibrations that can be observed in the IR spectrum of caffeine :

i) asymmetric, ii) symmetric, iii) wagging, iv) twisting, v) scissoring, vi) rocking

  • while the observable stretching frequencies are ; 1700, 1300, 2900, 1500 and 3000.

Caffeine is a polyatomic molecule ( contains more than two atoms bonded via covalent bonds )  therefore its atoms can vibrate in three dimensions ( x, y, z ).therefore the bond vibrations that can be observed in the IR spectrum of caffeine are :  asymmetric, symmetric, wagging, twisting, scissoring, and rocking.

The observable stretching frequencies that are in the IR spectrum of caffeine ; C = O is 1700 ,  C - H is 1300,  C -H is 2900,  C -N is 1500, and N -H = 3000.

Hence we can conclude The bond vibrations that can be observed in the IR spectrum of caffeine : i) asymmetric, ii) symmetric, iii) wagging, iv) twisting, v) scissoring, vi) rocking and the observable stretching frequencies are ; 1700, 1300, 2900, 1500 and 3000.

A cylinder, with a piston pressing down with a constant pressure, is filled with 2.10 moles of a gas (n1), and its volume is 46.
olga2289 [7]

Answer:

The volume is  V_2 =15.33 \  L

Explanation:

From the question we are told that

    The number of moles of the gas is  n_1 = 2.10 \  moles

      The volume of the gas is  V  =  46.0 \  L

        The  of moles of the gas that leaked is  n_2 =  0.700 \  mol

Generally from the ideal gas law

      PV  =  nRT        

Generally at constant pressure and temperature

        \frac{V}{n}  =  constant

So   \frac{V_1 }{n_1}  = \frac{V_2 }{n_2}

=>    V_2 = \frac{ V_1 *  n_2 }{ n_1}

=>    V_2 = \frac{  46.0 *  0.700  }{ 2.10 }  

=>    V_2 =15.33 \  L
