(a)
Interpretation:
For the given set of measurements the significant figures has to be determined.
Concept introduction:
Significant figures: The digits having a meaning in a given number are called as significant figures.
Significant figures – calculation rules
- Significant figure is a non-zero number (4443.2 has five significant figures)
- Zero’s placement in between non-zero number are significant figures (40005 has five significant figures).
- Zero’s before the non-zero number are not significant number (0.00040005 has five significant figures).
- Zero’s after the non-zero number are significant in case of that number contains decimal point (4.5000 has five significant figures).
- Zero’s after the non-zero number may or may not be a significant figure in case of that number does not have a decimal point (500 may have 1, 2 or 3 significant figures). In this cases use scientific notation to avoid ambiguity.
To give: The significant figures for the given measurement

- Can you please help mne with this problem. Im a visual person, so can you redraw it, potentislly color code and then as well explain it. I know im given CO2 use that to explain to me, as well as maybe give me a second example just to clarify even more with drawings (visuals) and explanations.arrow_forwardPart 1. Aqueous 0.010M AgNO 3 is slowly added to a 50-ml solution containing both carbonate [co32-] = 0.105 M and sulfate [soy] = 0.164 M anions. Given the ksp of Ag2CO3 and Ag₂ soy below.
