An unknown compound contains 75.69% carbon, 8.80% hydrogen, and 15.51% oxygen by mass. A mass spectrometry analysis reveals that
tiny-mole [99]

Answer:

Molecular formula is C₂₆H₃₆O₄

Explanation:

The compound is 75.69 % C, 8.80 % H and 15.51 % O. This data means, that in 100 g of compound we have 75.69 g, 15.51 g and 8.80 g of, C, O and H, respectively. We know the molar mass of the compound, so we can work to solve the moles of each element.

In 100 g of compound we have 75.69 g C, 15.51 g O and 8.80 g H

In 412 g of compound we would have:

(412 . 75.69) / 100 = 311.8 of C

(412 . 15.51) / 100 = 63.9 g of O

(412 . 8.80) / 100 = 36.2 g of H

Now, we can determine the moles of each, that are contained in 1 mol of compound.

312 g / 12 g/mol 26 C

64 g / 16 g/mol = 4 O

36 g / 1 g/mol = 36 H

Molecular formula is C₂₆H₃₆O₄

How many moles of nitrogen gas will occupy a volume of .5L at 1.0atm and 298K
hammer [34]
 <span>Use the Ideal law Equation :

P.V= n.R.T 

V = 0.5 L

P = 1.0 atm

</span><span>R= 0.0821 L*atm/mol*K 
</span>
<span>n = R*T/P*V 

</span><span>P*V= n*R*T 
</span>
1.0 * 0.5 = n *<span>0.0821*298

0,5 = n* 24.4658

n = 0,5 / 24.4658

n =0.0204 moles
