drek231 [11]
It is given in the problem that out of 25 students in Hansels class 17 students went to the class trip to the zoo. From the above information it is easy to find the percentage of students that went for the class trip to the zoo.
Total number of students in the class = 25
Number of students that went for the class trip to the zoo = 17
Then
Percentage of students that went to the zoo = (17/25) * 100
                                                                       = (17 * 4) percent
                                                                       = 68 percent
So 68% of the students in Hansels class went for the class trip to the zoo.

How many moles of oxygen are required to burn 3.0 mole of C10H8 (naphthalene)?
astra-53 [7]

Answer: 36 moles oxygen

Step-by-step explanation:

C10H8 + 12O2 ====》 10CO2 + 4H2O

From the equation of the reaction,

1 mole of napth requires 12 moles of O2

3 moles of napth would require x moles O2

X = (3 * 12) / 1

X = 36 moles of oxygen.

Therefore 3 moles of naphtalene (C10H8) would require 36 moles of oxygen
