Homework Help: Lab- Calculate Relative Uncertainty, How many sig figs?

  1. Jun 11, 2014 #1
    1. The problem statement, all variables and given/known data

    Calculate the relative uncertainty in the mass
    mass (M) = 1.0 grams

    2. Relevant equations

    [itex] \frac{\delta M}{M}[/itex]

    3. The attempt at a solution

    [tex]\delta M = \pm0.05g[/tex]
    [tex]\frac {0.05g}{1.0g} = 0.05[/tex]

    [tex]\frac {0.05g}{1.0g} = 0.050[/tex]

    Which one has the appropriate amount of sig figs?

    thanks for your help :)

    The units cancel when dividing grams by grams !
