WebDec 23, 2024 · Most people don’t know how many sig figs in logarithms there actually are. The answer is: it depends. The number of sig figs in a logarithm is equal to the number of digits in the base 10 logarithm of the number. For example, the base 10 logarithm of 100 is 2, so the number of sig figs in logarithms for 100 is 2. WebCAUTION: To figure out the number of decimal places, the number MUST be first expressed in decimal form, rather than in exponential form!!! For example, 4.2 has 2 sig. fig., so log 4.2 should have only 2 decimal places: 0.62 4.25 has 3 sig. fig., so log 4.25 should have 3 decimal places: 0.628 0.03 has 1 sig. fig., so log 0.03 should have 1 decimal place: -1.5 …
Web4. Logarithms All logarithms have two parts. The decimal part is called the mantissa . The digits in the mantissa are the only significant figures in a logarithm. The integer, or characteristic , is the power to which the base (in the following examples, 10) is raised when writing the number in scientific notation. It is an exponent and therefore WebAn aqueous solution of 0.22 M Mg(NO2)2 has a pH of Remember # number of sig figs for logarithms rule: (# of sig figs in concentration) = (digits after decimal).

Weba) multiply 3.1 by 3.5. Each number has two significant figures therefore the answer can have a maximum of two significant figures. 3.1 x 3.5 = 10.85. However 10.85 has four significant figures and therefore must be rounded to 11, which has two. So in this case the correct answer is 11.
