The formula for the t-test for dependent means is (M1-M2)/(SD/sqrt(n)). The n in this formula represents the number of pairs of observations, as the t-test for dependent means is used when we have two sets of scores that are related to one another (e.g., before and after treatment scores from the same participants). Therefore, we need to know the number of pairs of observations to calculate the standard error of the difference between the two means.
