A new boron hydride, B x H y , has been isolated. To find its molar mass,

Question:

A new boron hydride, B_xH_y, has been isolated. To find its molar mass, you measure the pressure of the gas in a known volume at a known temperature. The following experimental data are collected:

Mass of gas = 12.5 mg Pressure of gas = 24.8 mm Hg Temperature = 25°C Volume of flask = 125 mL

Which formula corresponds to the calculated molar mass?
(a) B₂H₆
(b) B₄H₁₀
(c) B₅H₉
(d) B₆H₁₀
(e) B₁₀H₁₄
