Idon't know how to solve for concentration:
if it requires 25.0 milliliters of 1.0 molar hcl to neutralize 45.0 milliliters of naoh, what is the concentration of the naoh solution?

balanced equation: naoh + hcl yields nacl + h2o

0.56 m naoh

0.82 m naoh

1.1 m naoh

1.8 m naoh

The diagram below shows a cell placed in a solution.a cell is shown placed inside a beaker. it is labeled cell. the solution inside the beaker is labeled 40% salt solution and the solution inside the cell is labeled 20% salt solution.only water is allowed to move in and out of the cell. what will most likely happen to the cell? it will expand as water moves out of it. it will shrink as water moves out of it.it will expand as water moves into it. it will shrink as water moves into it.
