A solution of potassium hydroxide (KOH) was titrated against a solution of hydrochloric acid. It took 35cm3 of the hydrochloric acid to completely neutralise the potassium hydroxide. Work out how many moles of acid there were in this volume if the concentration of the acid was 2mol/dm³.

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.
