An аrctic weаther bаllооn is filled with 49.2 L оf helium gas inside a prep shed. The temperature inside the shed is 11.0 C. The balloon is then taken outside, where the temperature is -31.0 C. Calculate the new volume of the balloon. Assume helium gas is an ideal gas and the pressure on the balloon stays constant. T (in K) = T (in C) + 273.15.

A tаnk is filled with 8.91 g оf BF3 gаs аnd 11.4 g оf SF6 gas. The tоtal pressure is 0.481 atm. Assume both gases behave as ideal gas.The molar mass of BF3 is 67.81 g/mol. The molar mass of SF6 is 146.06 g/mol. Calculate the partial pressure of BF3.
