Significant figures addition

From McCarty, NBS Rep. 9762, 1970. Reproduced by permission. The source contains values for further temperatures and for other functions, usually to additional significant figures. 

We have expressed each result with an additional significant figure, written as a subscript, so that we can see the effect of rounding. With the beads available, we can produce 163 necklaces, since we are unable to produce a fraction of a necklace. 

Ouch. A bit of careful arithmetic shows that the speed in the larger tube is 0.144 m/s (we ll keep one additional significant figure in this intermediate answer to prevent a rounding error). If the radius of the large tube is 0.010 m, the area is 3.14 x 10 4 m2. Therefore, the flow rate is ... 

If additional significant figures are needed, 273.15 can be used in place of 273. The standard temperature for gases is 0°C, which is 273 K, a benchmark temperature used when comparing volumes of gases. No degree symbol is used with Kelvin temperatures. More information about the Kelvin temperature scale appears in the discussion of Charles law. 

The accuracy ranges from 1% in the best cases to 5 to 10% in the worst cases. Additional significant figures are included in the table to facilitate interpolation. 

We carry an additional significant figure throughout this calculation to minimize rounding errors. The initial molarity of SO2CI2 is ... 

The charges of the M and X ions are -i-3 and -2, respectively (are other values possible ). We first calculate the number of moles of M2X3 that dissolve in 1.0 L of water. We cany an additional significant figure throughout this calculation to minimize rounding errors. 

We can calculate Kp using the following equation. We carry additional significant figures in the calculation to minimize rounding errors when calculating Kp. 

We cany additional significant figures throughout the remainder of this calculation to minimize rounding enors. 

Step 1 AG° was calculated in part (a). We must calculate Qp. We cany additional significant figures in this calcnlation to minimize rounding errors. 

The value of 12.011 found in the periodic table is obtained using additional significant figures on the isotopic abundance numbers.
