Write the definition of a function print grade, which takes one parameter containing a string value and returns nothing. the function prints "grade: " followed by the string parameter.

def print_Grade(grade):

print("Grade: ",grade)

Explanation:

The above code segment is a function that takes grade as a string parameter and returns nothing.

The line 1 starts with def keyword.

The keyword is used to start a function and the function will be uniquely identified with it.

The name of the declared function is print_Grade

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
