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:

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.

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.
