When a sample of a newly discovered gaseous silicon-fluorine compound was collected over water at 25 °C, the total gas pressure is
582.4 mmHg and the volume is 125.0 mL. Analysis of 1.49 g of the compound shows that it contains 42.4 mass % silicon. Use this
information to answer the following questions.
For calculations, provide answers as numbers (not scientific notation) without units; for full credit, the last digit must be within 1 of the
true value and the number of significant figures must be correct.
For text based questions, do not worry about subscripts or superscripts.
