6. Challenge yourself: Suppose you wanted to make 100 grams of water. A.
10
What is the molar mass of water (H2O)?
B.
How many moles of water are in 100 grams?
5.5
C. How many moles of hydrogen will you need?
10
D.
How many moles of oxygen
will
you
need?
80
E.
How many grams of hydrogen and oxygen will you need?
Ну

Is your answer reasonable? Why or why not?

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.

sup bro, im dumb, but this is what i found xd

"the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface"
