Convert each of the following measurements to the indicated units. 1.450 ug/uL to ng/mL

You want to produce a 50 g sample of glucose by evaporating to dryness a quantity of glucose solution containing 8% glucose by mass. The density of the glucose solution is 1.15 g/mL. What volume of glucose solution, in liters, must be taken for this purpose?

The volume of a solution was measured in a graduated cylinder (shown below), and the density of solution is measured to be 13.5 g/ml, what is the mass of the solution? (make sure to record volume of the liquid with correct sig figs, without units) 50 ml 45 ml 40 ml

how do i approach this

Convert the following measurement. Thank you!!

A vial of amoxicillin contains 540. mg in 3.4 mL of solution. Part A What volume of the solution contains 190 mg of the drug? Express your answer to two significant figures and include the appropriate units. HÀ Volume = Value Units

A buret contains an unknown solution. mL Initially the buret was filled with the solution so that it read 12.46 mL and the balance below read 111.71 g with an 21 empty beaker on it. Some volume of the solution was dispensed into the beaker. Use the measurements from the buret and the balance to 22 determine the density of the unknown solution. d = g/mL 31.47

A student needs to determine the density of an irregularly shaped object. This student prepares a solution mixture where the object is suspended. The collected data is shown in the table below. Liquid Dichloromethane Methanol 0 Density mL g mL 1.3340 0.791 Volume (mL) 9.28 Determine the density of the object. Be sure your answer has the correct number of significant digits. 6.15 0 X S

A student needs to determine density of a liquid. The student determines mass of an empty.flask to be 251.21 g and then adds 224 mL of liquid to it. The mass of the flask with liquid is 451.13 g. What is the density of the solution in units of g/mL?
