Q. Friday night’s hockey game was attended by 180 students. This is about 60 % of the school’s population. What is the total pop
OlgaM077 [116]

Answer:

The total population of the school is 300 students.

Step-by-step explanation:

Considering, we are working with percentage we can use the equation:

y = %x.

To fill in the equation you can use what you already know, 60% = 180

180 = 0.60x

To solve this, you can then divide both sides of the equation by 0.60. This will then give you your answer, 300 = x.

For checking, you can do 180 = 0.60(300) which will result in 180 = 180.

15. A photoelectron experiment is performed on a sample of silicon using photons with an energy
leonid [27]

Answer:

9.0×10^3K/moles

Step-by-step explanation:

ionization energy of these electrons = Energy of photons - kinetic energy of the electrons

Given

Kinetic energy of electron = 1.34×10^5

Energy of photons = 1.43 x 105 kJ/mole

Required

Ionization energy of these electrons

Ionization energy of these electrons = 1.43×10^5-1.34×10^5

ionization energy of these electrons = 0.09×10^5 kJ/mol

= 9.0 × 10^3 kJ/mol

Hence the ionization energy of these electrons is 9.0×10^3K/moles
