A mm is 0.1 of a cm, or there are 10mm in a cm. Multiplying the cm value by 10 gives us the length in mm. 500x10 is 5000 millimetres
There are 10 millimeters in 1 centimeter, so 500 centimeters is equivalent to 5000 millimeters.
C1 V1= C2 V2 500x10= 7.5xV2 V2= 666.6 Final vol= 666.6-500= 166.6
A paramecium cell ranges from about 50 to 350 µm in length
The mass of 1 molecule of water is approximately 18 atomic mass units. Therefore, the mass of 500 trillion molecules of water would be approximately 9 trillion atomic mass units, which is roughly 9 grams.
