Answer the following problems showing all work.<br> <br> <br> 1. A sample of urea contains 1.121g N, 0.161g H, 0.480g C and 0.640gO. What is the Empirical Formula?<br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> 2. A compound consists of 69.6% S and the rest of nitrogen. If the molar mass of the compound is 184g/mole, what is the MF and EF?<br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> 3. Determine the MF if the compound has an EF of <nowiki>NPCl</nowiki><sub>2</sub> and a molar mass of 348g/mole? <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> Answer: 1) C<sub>1</sub>H<sub>4</sub>N<sub>2</sub>O<sub>1</sub>, 2) S<sub>4</sub>N<sub>4</sub>, 3) P<sub>3</sub>N<sub>3</sub>Cl<sub>6</sub><br>
