 Exercise Answer What volume of water should be added to 400ml of a 0.1M NaOH solution in order to change the concentration to 0.075M NaOH. 535 ml 135 ml 400 ml 588 ml 600 ml What volume of water should be added to 80ml of a 0.6M NaOH solution in order to change the concentration to 0.07M NaOH. 535 ml 135 ml 400 ml 588 ml 600 ml 606 50mls of water are added to 230mls of a 0.1M NaOH solution. What is the concentration of the solution ? 0.82 M 0.082 M 1.082 M 1.82 M 0.008 M 0.0167 M 0.167 M A 1 litre vessel containing 0.5M NaOH solution is connected to a 2 litre vessel containing pure water via a valve (as shown above). When the valve is opened the solute dissolves evenly in both vessels. A sample of water is taken from the 2 litre vessel and analysed. What is the concentration of the sample? 0.82 M 0.082 M 1.082 M 1.82 M 0.008 M 0.0167 M 0.167 M A 1 litre NaOH solution is connected to a 6 litre vessel containing pure water via a valve (as shown above). When the valve is opened the solute dissolves evenly through both vessels. A sample of water is taken from the 6 litre vessel and analysed. If the concentration of the sample was found to be 0.45M calculate the concentration of the original solution in the 1 litre vessel? 0.82 M 0.082 M 1.082 M 1.82 M 0.008 M 0.0167 M 0.167 M 3.15 M What volume of water should be added to 200ml of a 0.01M NaOH solution in order to change the concentration to 0.0055M NaOH. solution  164 mL What volume of water should be added to 400ml of a 0.9M NaOH solution in order to change the concentration to 0.075M NaOH. solution  1.4L
