Question 39 (1 point) What is the volume (in L) of 4.20 grams of CO2 gas at STP? (
molar masses are,
Carbon = 12.01 g/mol, and oxygen - 16.00 g/mol)
Your

volume = 2128L

Explanation:

volume at stp = 22.4dm³ =22400L

CO2 = 12 + 2(16) = 44

4.20/44 = volume/22400L

0.095 = volume/22400L

volume = 0.095 x 22400

volume = 2128L

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.
