The answer is 2 because you have to divide these numbers.<span />
Soil
profile
Soil
profile is the vertical sequence of the layers of soil. Furthermore, there are
actually six layers of the soil which involves the organic matter, -where most
humus is present-, surface soil, the subsoil, the parent rock, and the bedrock
as the innermost and core layer of the soil. In addition each soil layer has
three to four soil horizon. These horizons are the physical features of the soil,
mainly the texture, color and composition.
Answer:
Identify the "given" information and what the problem is asking you to "find."
Given : Cl2O7
Find: % Composition (% Cl and %O)
List other known quantities.
Mass of Cl in 1 mol Cl2O7 , 2 Cl : 2 x 35.45 g = 70.90 g
Mass of O in 1 mol Cl2O7 , 7 O: 7 x 16.00 g = 112.00 g
Molar mass of Cl2O7 = 182.90 g/mol
Particles in a solid are fixed in place.!!
Answer:
25/12 or about 2.083g/cm^3
Explanation:
The first step is to find the volume of the box. The formula for the volume of a rectangular prism is width*height*length, which in this case is 8*6*5=240 cubic centimeters. The formula for calculating density is mass/volume, which in this case is 500/240=25/12 or about 2.083 g/ cubic centimeter. Hope this helps!
