Water is placed in a graduated cylinder and the volume is recorded as 43.5 ml. a homogeneous sample of metal pellets with a mass of 10.88 g is added and the volume of the water now reads 49.4 ml. what is the density of the metal in g/ml.?
1 answer:
Density = mass /volume of the body. mass = 10.88 g, volume of the liquid displaced= 49.4-43.5=5.9 ml. density = 10.88/5.9=1.844 g/ml~1.84 g/ml The volume displaced is exactly the same as that of the body (The Eureka fro Archimedes!)

D. quantitative data can be recorded.
It contains 5 ions.
Hope that helped!!
Yo sup??
We know that
pH=-log[H+]
[H+]=10^(-pH)
pH=5
therefore
[H+]=10^(-5)
The medium is acidic
Hope this helps.
Adenine pairs with Thymine and Guanine pairs with Cytosine. I remember this by the car (C) goes in the garage (G). Then A and T are the only ones left, so they pair together.
