Fluorine is so reactive that it forms compounds with materials inert to other treatments. When 0.622 g of platinum is heated in fluorine, 0.985 g of a dark red, volatile solid forms.

When 0.378 g of this red solid reacts with 0.161 g xenon gas, 0.539 g of an orange-yellow solid forms. What is the empirical formula of this product, the first to contain a noble gas?

Solutions

Expert Solution

Molar Mass of Platinum = 195.084g/mol

Mass of Platinum = 0.622g

No of mole of Platinum = 0.622g/195.084g = 0.003188g

Mass of dark red compound = 0.985g

Mass of Flourine reacted = 0.985g - 0.622g = 0.363g

Molar mass of Flourine = 18.998g

No of mole of Florine reacted = 0.363g / 18.998g = 0.019107

Ratio of flourine / platinum

Flourine / Platinum = 0.019107/0.003188= 5.993 = 6

So , the empirical formula of dark red compound is PtF₆ ( Platinum hexaflouride )

Molar mass of PtF₆ = 309.07g/mol

Mass of PtF₆ reacted = 0.378g

No of mole of PtF₆ reacted = 0.378g/309.07g =0.001223

Mass of Xe gas reacted = 0.161g

Molar mass of Xe = 131.296g/mol

No of mole of Xe gas reacted = 0.161g/131.296g = 0.001226

Ratio of PtF₆/Xe is 1:1

Therefore ,

the empirical formula is XePtF₆ ( Xenon hexaflouroplatinate )

Based on the text reading and other materials used, explain when a manager would use cost-volume-profit analysis and sensitivity analysis. In addition to the discussion, suppose a company decided to automate a production line. Explain what effects this would have on a company's cost structure using CVP terminology. Could these changes have any possible negative effect on the firm? One of the focuses of CVP analysis is breakeven analysis. Specifically, CVP analysis helps managers of firms analyze what it will...
