"A metal with a mass of 107.1g was placed into a graduated cylinder and completely submerged. The water level went from 22.5mL to a volume of 36.1mL. What is denisity of the metal? round your answer to two decimal places omit trailing zeroes Given the following table what is the identity of the metal? metal Density Magnesium 1.74 Aluminium 2.70 Titanium 4.50 Zinc 7.14 Iron 7.86 Nickel 8.90 Copper 9.96 Lead 11.34 13.55 Mercury 19.32 Gold

A titration of vinegar was conducted using 0.756 M NaOH. In total, 30.54 mL of NaOH were added when the solution turned pink. How many moles of NaOH were involved in the reaction? Write your answer in standard notation with the correct number of significant figures. You do not need to include units.

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

A lab assistant needs to neutralize a 3.1 M solution of HCI. If there are 350 mL of solution, what volume, in Liters, of a 1.8 M NAOH solution would have to be used? (Hint: You will need to write out the equation and balance it first.) Be sure to report your answer to the correct number of significant figures. Do not report the units (L) in your answer.
