A radioactive tracer, I believe. Someone check that lol.
Answer:
24.5%
Explanation:
You just add up the atomic masses.
Ca - 40.078
Cl2 - 35.4527 x 2 = 70.9054
------ 110.9834
H4 - 1.00794 x 4 = 4.03176
O2 - 31.9998
------ 36.03056
TOTAL - 147.01396
So the water is 36.03056/147.01396 = .245082576 but that is only accurate to three decimals (because the mass of Ca was only given to three decimals) so we write .245 and that is 24.5%
This is not my answer but I found it on Yahoo answers and it was answered by Anonymous.

Answer:
Force of Tension = 1832.8 N
Explanation:
Any mass of object supported or pulled by a rope or cable is subject to a force of tension. Since the mass is raised by a cable, tension is involved.
Mathematically,
Tension = mass × gravity(9.8 m/s²)
Tension can be represented as
T = (m × g) + (m × a)
Where g is the acceleration due to gravity of the object the cable is supporting and a is the acceleration on the object the cable is supporting. And m is the mass of the object.
mass = 158 kg
a = 1.8 m/s²
g = 9.8 m/s²
T = mg + ma
T = m(g + a)
T = 158(9.8 + 1.8)
T = 158 × 11.6
T = 1832.8 N
