Measurement and Matter Adding or subtracting and multiplying or dividing measurements 1/3 B A chemistry student must write down in her lab notebook the concentration of a solution of sodium hydroxide. The concentration of a solution equals the mass of what's dissolved divided by the total volume of the solution. Here's how the student prepared the solution: The label on the graduated cylinder says: empty weight: 7.2 g . She put some solid sodium hydroxide into the graduated cylinder and weighed it. With the sodium hydroxide added, the cylinder weighed 63.517 g. . She added water to the graduated cylinder and dissolved the sodium hydroxide completely. Then she read the total volume of the solution from the markings on the graduated cylinder. The total volume of the solution was 91.0 mL. What concentration should the student write down in her lab notebook? Be sure your answer has the correct number of significant digits. g-mL G

Blood alcohol content is a measure of alcohol in the blood as a percentage. It is calculated in grams per 100 mL of blood, so a BAC of 0.08 means your blood is 0.08% alcohol by volume. what is the total mass of alcohol (in grams) that is present for the same adult male whose total blood volume is 5.6L?

Percent by Mass= Mass of Solute x100 Percent by volume and Percent by Mass calculations Mass of Solution Volume of Solute Name: Percent by Volume= -x100 Volume of Solution 1. 1. Calculate the percent by volume if 56.7 ml of alcohol is added to 540 ml of water. (Remember to add both solute and solvent to get the total volume of solution to put on the bottom.) 540 15.23 2 Calculate the percent by mass if 35.0 grams of NaC! is added to 455 grams of water to make a salt solution. 3. Calculate the percent by volume if 15.5 ml of HCI is added to 1.0 Liter of water. 4. Calculate the amount of water needed to make a 5% solution of alcohol, if you have 25 ml of alcohol? (Hint: first you will need to find the total amount of solution needed. then subtract the 25 ml from that.)
