Answer;
A. letters to tuna companies
The use of dolphin-safe nets for catching tuna was started because of letters to tuna companies.
The use of dolphin-safe fishing methods was started because lots of dolphins were drowning in nets used to catch yellow fin tuna. The method was a new plan that the US had created in order to increase the tuna shortage that was happening in the country.
<span>V = 150.0 mL = 0.15 L
c = 1.70 M
</span>m=?
For the purpose, the equation for molar concentration is necessary:
c=n/V
From the equation we can determine the number of moles:
n= cxV = 1.70M x 0.15L = 0.255 mole
Now we can calculate the mass:
m = nxM = 0.255 x 119= 30.34 g is necessary
