10cc as 1ml is 1cc is 1cm3
Density = Mass / Volume So, density of an object with a volume of 10ml and a mass of 20 grams is = m / v = 20grams/10ml = 2g/ml
0.34 ml on a syringe represents 34 units on the syringe's scale. To measure it, draw the plunger up until the liquid reaches the 0.34 ml mark on the syringe.

The density of the object is 40 g/ml. This is calculated by dividing the mass (400g) by the volume (10ml). Density is a measure of how much mass is contained in a certain volume.
The density of the object is calculated by dividing the mass by the volume. In this case, the density would be 2 g/ml.
The density of the object is 0.1 g/ml. This is found by dividing the mass (1g) by the volume (10ml).
The mass in the syringe, as you push down the plunger.
The density is 10 kg/mL
Density = Mass/Volume = 15/10 = 1.5 g per mL
The same way you read ANY syringe. From www.wikipedia.com (http://en.wikipedia.org/wiki/Syringes), if you click on the image of the 10ml syringe, you'll see the markings on the barrel. You measure the units of fluid from the needle side back to the plunger - so as you pull back the plunger you draw in "x" ml's of fluid as marked from the needle back. Standard safety procedures surrounding the use of a syringe should always be followed, and in no way is this short answer a full and complete explanation of how to correctly/safely use a syringe.
