Phosgene is a highly toxic gas made up of carbon, oxygen, and chlorine atoms. Its density at 1.05 atm and 258C is 4.24 g/L. (a)

VikaD [51]

Answer:

Molar mass = 99 g/mol

Explanation:

Phosgene contains carbon, oxygen and chlorine atoms. Its molecular formular is; COCl2

The molar mass is given as the sum off the individual atomic mass of the elements in the compound.

Molar mass = C + O + 2Cl

Molar mass = 12 + 16 + 2(35.5)

Molar mass = 99 g/mol

Harvey kept a balloon with a volume of 348 milliliters at 25.0˚C inside a freezer for a night. When he took it out, its new volu

ad-work [718]

Initial volume of the balloon = $V_{1}$ = 348 mL

Initial temperature of the balloon $T_{1}$ = $25.0^{0}C + 273 = 298 K$

Final volume of the balloon $V_{2}$ = 322 mL

Final temperature of the balloon = $T_{2} = ?$

According to Charles law, volume of an ideal gas is directly proportional to the temperature at constant pressure.

$\frac{V_{1} }{T_{1} } =\frac{V_{2} }{T_{2} }$

On plugging in the values,

$\frac{348mL}{298 K} =\frac{322 mL}{T_{2} }$

$T_{2} =276 K$

Therefore, the temperature of the freezer is 276 K
