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> <center><b>Do Not Use Temperature Value in Determining Sig Fig in Answer</b></center><br> 1. How many grams of Calcium nitrate do you need to make 364ml of a 0.153M Calcium nitrate solution?<br> <br> 2. What mass of Barium fluoride do you need to get a 0.629m solution if you have 452grams of water?<br> <br> 3. What mass (in kilogram) of a water do you need to have to make a 2.50m Zinc sulfate solution if you have 9.08 grams of the solid.<br> <br> 4. How many grams of Ammonia do you need to add to 275g of water to a make saturated solution at 57.degC? (see attached table for Solubility values). Please write the Solubility of the solution first.<br> <br> 5. What is the molality (m)of a solution that has 3.45grams of Sodium carbonate and 755grams of water?<br> <br> 6. What is the molarity of a solution if you have 43.5grams of Strontium acetate in a 1.76L solution?<br> <br> 7. What volume of a solution do you need to make a 0.675M Aluminum carbonate solution if you have 4.54 grams of the solid.<br> <br> 8.
