Defor- mity as a factor in the ANOVA was also significant (F1,38 ¼ 4.398, p ¼ 0.043); however, there was a significant interaction between age and deformity (F1,38 ¼ 5.670, p ¼ 0.022). There was a steeper association between age and BALP for the deformed birds, and so in the younger age range,

Exact quantities are counting numbers or metric relationships (unit analysis) that are known precisely with unlimited (i.e. infinite) sig. figs. Measured quantities come from measurements and are subject to uncertainty (need to express with sig. figs.). 2.Simplify (2.55 x 103) (6.5 x 10-10) = 9.8 x 10. 4 (1.7 x 10-11) 3.Given that 2.2 lb. = 1.0 kg:

pOH = - log (1.852 x 10-11 ) = 10.73 (has 2 sig figs since 5.4 has two sig figs) If you understand logs well you remember that if dividing numbers is the same as subtracting their logs. So a quick way to get pOH if pH is know is the following. pOH = 14.00 – pH = 14.00 - 3.27 = 10.73 2.
