You deposit money today into an account at 6.5 percent interest how long to double your money?

About 11 years. (One quick way to find out how fast your money will double is through the Rule of 72. Divide 72 by the interest rate you're getting--in this instance, 6.5%. 72 divided by 6.5 = 11.07. So, it will take a little over 11 years for your money to double.)
