8 0

Answer:

Hello, I can help!

Explanation:

<u>Molecular Formula:</u> ZnSO4. 7H2O or H14O11SZn

<u>Molecular Weight: </u>287.6 g/mol

<h2><u>Computing molar mass (molar weight)</u></h2>

<u>Functional groups:</u> D, Ph, Me, Et, Bu, AcAc, For, Ts, Tos, Bz, TMS, tBu, Bzl, Bn, Dmg

<u>Common compound names.</u>

Examples of molar mass computations: NaCl, Ca(OH)2, K4[Fe(CN)6], CuSO4*5H2O, water, nitric acid, potassium permanganate, ethanol, fructose.

-Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)

-Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.

God bless you!

  =2.36  x6/2= 7.08  moles

the  %  yield  =  actual  yield/  theoretical  yield  x  100

that  is    6.14/7.08  x100=  86.72%
