Answer the following problems showing all work.<br> <br> 1. If I have a potassium nitrate solution @56degC, how many grams of H<sub>2</sub>O do I need if I have 653g of potassium nitrate.?<br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> 2. How many grams of sodium carbonate do you need to add to make 750.ml of a 0.875M solution?<br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> 3. How many kg H<sub>2</sub>O do I need to add to 0.457m (molality) calcium nitrite solution where 2.45g of the solute was added?<br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> 4. What is the new volume, if I dilute 2.57L of a 0.745M solution to a 0.500M solution?<br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> Answer: 1) 695g H<sub>2</sub>O (assuming S = 94g/100g) , 2) 69.6g Na<sub>2</sub>CO<sub>3</sub>, 3) 0.0406kg, 4) 3.83L<br> <Br>
