The first titration is done to standardize the silver nitrate solution. so first determine the number of moles of kcl used. then, use the chemical reaction kcl+agno3→agcl(s)+k++no3− to determine the moles of agno3 (notice the 1: 1 ratio). next, calculate the molarity of agno3 using the volume, 61.9 ml . the second titration is done to find the nacl content in the chip. since only 46.9 ml of agno3 was used in this titration, you must find the moles of agno3 in that volume. then, use the chemical reaction agno3+nacl→agcl(s)+na++no3− to determine the moles of nacl (notice the 1: 1 ratio). next, convert moles of nacl to grams using its molar mass. finally, take the mass of salt (which is for the given mass of filtrate), and scale it per serving.

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
