How many structural isomers does CH4 have?
a. two
b. five
c. three
d. one

Hello,  there! your Answer is Below

My Answer Would be A. Two

Explanation:

Structural Isomers are molecules which have the same molecular formula but have different connectivities

Hope this helps you!!

Have a great day!!!

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
