What is the grams of carbon dioxide needed to occupy a container that is 9 liter at 32 degrees celsius and 35 kpa

44.01 g/mol.

Explanation:

We can use the general law of ideal gas: PV = nRT.

where, P is the pressure of the gas in atm (P = 35.0 kPa/101.325 = 0.345 atm).

V is the volume of the gas in L (V = 9.0 L).

n is the no. of moles of the gas in mol (n = ??? mol).

R  is the general gas constant (R = 0.0821 L.atm/mol.K),

T is the temperature of the gas in K (T = 32.0°C + 273 = 305.0 K).

∴ n = PV/RT = (0.345 atm)(9.0 L)/(0.0821 L.atm/mol.K)(305.0 K) = 0.124 mol.

∴ n = mass/molar mass

∴ mass = (n)(molar mass) = (0.124 mol)(44.01 g/mol) = 5.457 g.

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
