When 7.6 grams of LiBr is dissolved how many moles of cation are produced?

Number of grams in 2.0 moles of magnesium chloride?
The formula of magnesium carbonate is MgCO3. It therefore has one atom each of magnesium and carbon and 3 atoms of oxygen. The gram molecular weight is therefore 24.305 + 12.011 + 3(15.999) = 84.313. This answer to the problem is twice this value, 168.626 grams, if the number "two" is considered to be exact.
How many significant figures are in the number 54100?
Three. All non-zero digits are significant, as are zeroes between them, and zeroes after a decimal point. The entire question about sigfigs is "what digits can you be confident are not rounded off?" The answer is three because you cannot prove that this is not rounded to the nearest hundred. You can only be sure that the three digits (405) are all correct and even the 5 might be rounded off. If it were 40500.0, then all six digits would be SigFigs because that is showing exactness. ■

34.872 to 1 significant figure?
34.872 rounded and chopped to 1 sig fig is 30. The previous answer 34.8 is wrong, 34.8 is 34.872 chopped to 3 sig figs.Any digit in a number that is not zero is classed as a significant figure e.g. your number above has 5 sig figs but if it was 30.072 it would only have 3 sig figs: 3, 7 and 2. When someone asks something to be taken to n sig figs they mean the first n significant figures of the number i.e. 103.42 to 2 sig figs would be 103, not 100.Also, incase you don't know what I mean when i used the terms rounded and chopped above, rounding is when you round the number either up or down to the nearest sig fig so your number rounded to 2 sig figs would be 35. Chopping however is when you take however sig figs you need and chop the rest of regardless of how close the n+1th digit is to a higher sig fig. e.g. 34.372 is 34 chopped to 2 s.f. but 34.872 is also 34 chopped to 2 s.f. in fact if a number is virtually the same as a higher number it will get chopped to a lower one e.g. 34.999999999999999 chopped to 2 s.f. is 34, not 35!
