Maximum Points. Based on the parameters chosen above, your puzzle will have a maximum score of points. To increase the point potential, select a greater grid size or difficulty level (or both). Final point scores will be awarded based on these factors as well as the total time it took you to complete the puzzle.
Method. 1) Work out the concentration in grams per dm3. 1 litre = 1 dm3 = 1000 cm3. 10Â·6 g of sod ium carbonate in 200 cm3 is equivalent to 10Â·6 x (1000 Ã· 200) g of sod ium carbonate in 1000 cm = 53 g per dm3. 2) Convert grams per dm3 into mol / dm3.To convert mass into moles use moles = mass Ã· RFM. RFM of ammonium nitrate (NH4NO3) is (1 x 14) + (4 x 1) + (1 x 14) + (3 x 16) = 80. moles = 120 Ã· 80 = 1Â·5. So, 120 g of ammonium nitrate dissolved in 1 litre of water = 1Â·5 mol / dm3. Example 2.) Convert grams per dm3 into mol / dm3. To convert mass into moles use moles = mass Ã· RFM. RFM of sod ium carbonate (Na2CO3) is (2 x 23) + (1 x 12) + (3 x 16) = 106. moles = 53 Ã· 106 = 0Â·5. So, 10Â·6 g of sod ium carbonate in 200 cm3 of water = 0Â·5 mol / dm3.
Molar Solutions A 1 molar solution is a solution in which 1 mole of a compound is dissolved in a total volume of 1 litre. For example: The molecular weight of sodium chloride (NaCl) is 58.44, so one gram molecular weight (= 1 mole) is 58.44g.If you dissolve 58.44g of NaCl in a final volume of 1 litre, you have made a 1M NaCl solution.To make a 0.1M NaCl solution, you could weigh 5.844g of NaCl and dissolve it in 1 litre of water; OR 0.5844g of NaCl in 100mL of water (see animation below); OR make a 1:10 dilution of a 1M sample.or example: The molecular weight of sodium chloride (NaCl) is 58.44, so one gram molecular weight (= 1 mole) is 58.44g. If you dissolve 58.44g of NaCl in a final volume of 1 litre, you have made a 1M NaCl solution.
