Period of oscilation is proprtional to the square root of Mass and inversely proprtional to the square root of k, the spring constant. It is independent of amplitude.
Use that fact to figure out the asnwers to those questions.
I dont have any other information though except for what is in the original question.
You should not need any more information than I already provided
