A 0.63-kg block is hung from and stretches a spring that is attached to the ceiling. A second block is attached to the first one, and the amount that the spring stretches from its unstrained length quadruples. What is the mass of the second block?
My work is as follows:
F=kx
mg=kx Since k is unknown, I chose to use 1
.63*9.8=1*x
x=2.52 kg
My answer is incorrect. What am I doing wrong?

.63 x 9.8 = 6.174 not 2.52
2.52 is the total weight. Subtract weight 1 from that to get your answer.
Sorry, showed my work incorrectly.
.63*9.8=1x
x=6.174
then F=k4x
m*9.8=1*24.696
m=2.52
.63*9.8=1x
x=6.174
then F=k4x
m*9.8=1*24.696
m=2.52
