Cyclohexane, a commonly used organic solvent, is 85.6% c and 14.4% h by mass with a molar mass of 84.2 g/mol. what is its molecu
puteri [66]

The molecular  formula of   organic solvent  is    <em>C6H12</em>


<h2>calculation</h2><h3>find the empirical formula first as in step 1 and 2</h3>

Step 1: f<em>ind the moles of C and H</em>

  • moles =  % composition/molar mass
  •       from periodic table molar mass of C= 12 g/mol while that of H= 1 g/mol
  • moles is  C is therefore = 85.6/12=  7. 13 moles
  •  moles of H=  14.4/1 - 14.4 moles

  Step 2:  <em>calculate the mole  fraction  by dividing each mole by smallest number of mole(7.13)</em>

  • that is C= 7.13/7.13 = 1

         H=  14.4/7.13 =2

the empirical formula is therefore = CH2

<h2>Then calculate the molecular formula from empirical formula</h2>

step 3: divide the  grams molar mass  by empirical formula mass

               empirical formula mass =  12+(1 x2) = 14 g/mol

    = 84.2/ 14 = 6

step 4: multiply  each of the subscript  within the empirical  formula with the value gotten in step 3

  • that is  [CH2]6 = C6H12  therefore the molecular formula = <u>C6H12</u>

Potassium is isotopic and has RAM of 39.5 work out the percentage abundance of each isotope in a given sample of potassium which
Troyanec [42]

Yo sup??

Let the percentage of K-39 be x

then the percentage of K-40 is 100-(x+0.01)

We know that the net weight should be 39.5. Therefore we can say

(39*x+40*(100-(x+0.01))+38*0.01)/100=39.5  

(since we are taking it in percent)

39*x+40*(100-(x+0.01))+38*0.01=3950

39x+4000-40x-0.4+0.38=3950

2x=49.98

x=24.99

=25 (approx)

Therefore K-39 is 25% in nature and K-40 is 75% in nature.

Hope this helps.

15 points + brainliest pls help :(
Komok [63]

Answer:

27 g

Explanation:

M(C6H12O6) = 6*12 + 12*1 + 6*16 = 180 g/mol

100 mL = 0.1 L solution

1.5 M = 1.5 mol/L

1.5 mol/L * 0.1 L = 0.15 mol  C6H12O6

0.15 mol * 180 g/1 mol = 27 g C6H12O6
