The volume is 12 mL (0.012 L)
Before the aluminum was added, the water reached 132mL. After it was added, it reached 144. That means the Aluminum takes up (144-132)= 12mL of space.
The density = mass/volume. If the aluminum bar has a mass of 78g and volume of 0.012L, 78/0.012=6,500 g/L
Answer:
I think the answer is Hydro sphere
Explanation:
Earth includes four components
Atmosphere
Biosphere
Hydro sphere
Geosphere
Here Hydro sphere is the goal of question
Answer:
0.322 moles
Explanation:
Given Mass, m = 100 g
The molar mass of Ca₃(PO₄)₂
Ca₃(PO₄)₂ = (3 x 40.08) + (2 x 30.97) + (8 x 16.00)
M = 310.18 g/mol
Let there are n number of moles,
n = given mass/ molar mass
So, there are 0.322 moles.
Liquid because it follows the shape of container
