You just confused the rules for adding and subtracting with sig figs for the rule for multiplying and dividing. 25 Celsius would be 298 Kelvins, and the rule for adding is to look at the least number of decimal places. Nothing before the decimal matters, and since neither 25 or 273 have any decimals, the answer is 298 K.
When you are multiplying two numbers, how do you determine the number of significant figures? You go with the lowest sig figs in your problem. so suppose you multiply 2.34 and 8.9574, in your product you should have 3 sig figs as
For this question: what is the boiling point of 0.39 mol ethylene glycol and 0.13 mol KBr in 155 g H2O? I got 102.1470968 and I tried it with 2 and with 3 sig figs but it's both wrong. I know that's the correct answer but I don't
for a manometer flask diagram, if ha = 134 mm, how do I convert to torr, Pa, and atm with the right amount of sig figs? Related to sig figs, how do I get the right amount of sig figs (which is 2) with 8339?
How many significant figures does 22.0, 0.22, 22. , 0.022? Im just confused as to the decimal addition to numbers and what the sig figs will be for them. If you don't mind can you please state some rules for sig figs that are
An equilibrium mixture of the following reaction was found to have [H2] = 0.020 M and [I2] = 0.020 M at 340°C. What is the concentration of HI? H2(g) + I2(g)--> 2 HI(g) Keq = 69 at 340°C I got .166 but it said check number of
