Significant Figures Although the rules for determining significant figures are fairly rigid, calculations for pH are somewhat special in that only the numbers to theright of the decimalare counted as sig figs! Acid Dissociation Constant (Ka) The acid dissociation constant is the portion of an acid...
Step 3: Plug the known variables into the equation and solve for path length. l=Aε⋅c=0.0300.0209(M−1cm−1)⋅0.137M Be sure to include units in calculations and round to reflect 2 significant figures. The path length of the solution is 10 cm....

be written carefully and correctly. Trapezoids only take into account the length of the parallel sides and the distance between them. The non-parallel sides are not of any importance in the area of trapezoid. So, before working on trapezoid figures, clearly picture ...
In real life, you can usually look up the density of commons liquids in reference books or online. While the calculation is simple, it's important to cite answer using the correct number ofsignificant digits. Also, pay attention to the units of your answer and make sure they agree with th...
It helps to write out the conversion and make sure units cancel. You might want to draw a line through them in complex calculations to keep track of active units. Watch yoursignificant figures. Chemistry professors are unforgiving when it comes to reporting an answer, even if you set up the...
Usually, you should give the final answer to 3 significant figures. Do not write your final answer as a fraction or in surd form. However, if the question asks you to give your answer to a specific number of significant figures, then you must follow the instruction, or if the question ...
1. How many moles of CaCl_2 are contained in 34.2 mL of 0.170 M CaCl_2 solution? 2. How many moles of Cl- are in the previous solution? 3. Silver nitrate, AgNO_3 reacts with CaCl_2 according to the eq Find the Delta H f...
