There is not enough room between questions to answer problems, so you need to do on separate page.<br> <center><b>You will need to USE MORE THAN 2 SHEETS OF PAPER</b></center><br> <br> 1) How many grams of Calcium nitrate ( Ca<sub>1</sub>(NO<sub>3</sub>)<sub>2</sub> ) do you need to make 364ml of a 0.153M Calcium nitrate solution?<br> <br> 2) How many moles of the solute do you have if you a 452ml of a 0.829M solution? <br> <br> 3) How many liters of solution do need to make a 1.56M Zinc sulfate ( Zn<sub>1</sub>(SO<sub>4</sub>)<sub>1</sub> ) solution if you have 18.1 grams of the solid.<br> <br> 4) What is the molarity of a solution if you have 43.5grams of Strontium acetate ( Sr<sub>1</sub>(C<sub>2</sub>H<sub>3</sub>O<sub>2</sub>)<sub>2</sub> ) in a 1.76L solution?<br> <br> 5) How many grams of caffeine (chemical formula is C<sub>8</sub>H<sub>10</sub>N<sub>4</sub>O<sub>2</sub>) do you need to weigh out to make 2.03L of a 0.847M solution.<br> <br> <br> <br> <P style="page-break-before: always"> <br> Answers:<br> 1) 9.13 g Ca<sub>1</sub>(NO<sub>3</sub>)<sub>2</sub><br> 2) 0.374moles <br> 3) 0.0721L solution<br> 4) 0.104M Sr<sub>1</sub>(C<sub>2</sub>H<sub>3</sub>O<sub>2</sub>)<sub>2</sub>(assume molar mass is 238g/mole)<br> 5) 334g C<sub>8</sub>H<sub>10</sub>N<sub>4</sub>O<sub>2</sub><br>
