Answer:
Density is 7.15 g /mL.
Mass is 445.2 g.
Explanation:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
Given data:
Mass of first zinc sample = 210.10 g
Mass of second zinc sample = 235.10 g
Combined volume = 62.3 mL
Density of combined sample ?
Mass of combined sample = ?
Solution:
Mass of combined sample = 210.10 g + 235.10 g = 445.2 g
density = mass / volume
density = 445.2 g / 62.3 mL
density = 7.15 g /mL
A for number 1 and C for number 2 im sorry i dont know the rest. :3
GPS- Global Positioning System, this is be found in cars
Google Maps- Finding the nearest Starbux, the map is generated by satellite data.
Phone calls and text messages- the signals go from your phone to the satellite and back down to whoever you're texting.
Hope this helps :)
Color, phase, odor and boiling point are the physical properties. Reactivity with oxygen depends on the chemical nature of object, thus, it is not a physical property. It is a chemical property.
