In chemistry lab student is determining the salinity of seawater using a conductivity meter. The student made standards of NaCl solutions and recorded the following data:
% Salinity Conductivity (ms)
0.10 1.83
0.20 3.62
0.30 5.49
0.40 7.09
0.50 8.76
The conductance of a 10 mL sample of unknown was found to be 5.82 ms.
Required:
a. Prepare a standard curve using the data above.
b. Determine the concentration of the unknown salt solution using the standard curve.

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
