The percent composition of carbon in C6H12O6 is:

1 answer:

8 0

To calculate percent composition, you first need to find the molar mass of C (carbon), H (hydrogen) and O (oxygen).
C is 12.01
H is 1.00
O is 16

Then multiply each by the number of atoms of each element in the formula (the number that comes after each element in the equation for example C6 means 6 carbon atoms.

C: 12.01 x 6= 72.06
H: 1x12= 12
O: 16x6= 96

Then add them up.
72.06+ 12+ 96= 180.06

Now find the percent composition of carbon.

72.06/ 180.06 x 100= 40.01%

So the answer is C 40%.

Answer:

1.40 atm

Explanation:

To answer this question we can use Gay-Lussac's law, which states:

P₁T₂=P₂T₁

When volume and number of moles remain constant.

P₁ = 1.11 atm

T₁ = 23°C ⇒ 23+273.16 = 296.16 K

T₂ = Boiling point of water = 100 °C ⇒ 100+273.16 = 373.16 K

P₂ = ?

We put the known data in the equation and solve for P₂:

1.11 atm * 373.16 K = P₂ * 296.16 K

P₂ = 1.40 atm

Educated Guess Here!

Since Br-80 does not exist, maybe that means Br-79 or Br-81 have very unequal abundances. For example, Br-79 may have 75% abundance whereas Br-81 may have 25% abundance.
