This calculator will conduct a complete one-sample t-test, given the sample mean, the sample size, the hypothesized mean, and the sample standard deviation. The results generated by the calculator include the t-statistic, the degrees of freedom, the critical t-values for both one-tailed (directional) and two-tailed (non-directional) hypotheses, and the one-tailed and two-tailed probability

By definition, Z score is: z=(x-mu)/sigma where x is your datum, mu is the mean of your population and sigma is its standard deviation. Basically, it's a measure of deviation from the mean in units of standard deviation. Unless I misunderstood your problem, I see no way you can calculate this number without knowing a standard deviation.
