Answer: PV/T = K(constant)

Or P1V1/T1=P2V2/T2

Explanation:

Combined law equation is the combination of three gas laws called Boyle's, Charlie's and Gay-Lusac's law.

It states that ratio of product of pressure and Volume to absolute temperature is equal to a constant

Boyle's law: PV=K

Charle's law: V/T=K

Gay-Lusac's law: P/T=K

What's the empirical and molecular weight of C14H22N4O8? What's the molecular formula of C14H22N4O8?
Inessa05 [86]

374u

187u

C₁₄H₂₂N₄O₈

Explanation:

To find the molecular weight of the compound C₁₄H₂₂N₄O₈ we simply sum that atomic masses of the given elements in the compound.

 The empirical weight is determined by using the simplest ratio of the elements involved in the compound;

Molecular weight of C₁₄H₂₂N₄O₈;

atomic mass of C = 12g/mol

                           H = 1g/mol

                            N = 14g/mol

                            O = 16g/mol

 Molecular weight = 14(12) + 22(1) + 4(14) + 8(16)

                                = 168 + 22 + 56 + 128

                                 = 374u

Empirical weight:

  Empirical formula:

                        C₁₄    H₂₂      N₄     O₈

                         14  :    22 :    4  :     8

   divide by 2:

                          7   :    11    :    2  :    4

     empirical formula  C₇H₁₁N₂O₄

     empirical weight = \frac{molecular weight}{2} = \frac{374}{2} = 187u

The molecular formula is the actual combination of atoms in a compound. so the molecular formula of the compound is C₁₄H₂₂N₄O₈

Explain, in terms of both atoms and molecular structure, why there is no isomer of CH3OH.
Jet001 [13]

Explain, in terms of both atoms and molecular structure, why there is no isomer of CH3OH.

There is no isomer of CH3OH or methanol because it contains only one carbon atom. And also, the structure is tetrahedral, having four substances attached to the carbon atom.
