a spring with a length of 22.0 centimeters hangs from a ceiling. when a 755gram mass is attached ti the spring, the spring strethes to 35.0 centimeters. what is the magnitude of the spring constant in N/m

The stretching distance is 35 22 = 13 cm
= 0.13 m
The force is M*g = 0.755kg*9.81 m/s^2
= 7.41 N
The spring constant is 7.41/0.13 = ___ N/m
