Density is the ratio of a substance's mass to its volume at a certain temperature and pressure.
Density = Mass/Volume
Since we are already given with the density and the volume, this would be easy to solve then. Just manipulate the equation to solve for mass. The equation becomes
Mass = Density*Volume
Mass = (11.35 g/cm³)(10 cm³)
<em>Mass = 11,350 g</em>
One
Balance the Equation.
This has been done for you or it is given. Anyway this step is finished, but it must always be done.
Two
Find the molar mass of C6H12O6
6C = 6 * 12 = 72
12H = 12*1 = 12
CO = 6 * 16 = 96
Mol Mass = 180 grams / mol
Three
Find the mols of C6H12O6
n = ???
Molar Mass = 180 grams / mol
given mass = 13.2 grams.
n = given mass / molar mass
n = 13.2 / 180
n = 0.07333333 mols.
Four
Find the mols CO2
1 mol C6H12O6 will produce 6 mols CO2
0.0733333 mols will produce x
1/0.073333 = 6/x Cross multiply
x = 0.073333 * 6
x = 0.4399 moles.
Five
Find the volume given the conditions for temperature and pressure are STP conditions.
PV = nRT
R = 0.082057
n = 0.43999
P = 1 atmosphere
T = 0 + 273 = 273
V = ???
1 * V = 0.43999 * 082057 * 273
V = 10.2 L
Answer: B
Note if you give out Brainly awards I'd sure appreciate one. This was a lot of typing
Well homogenous is the same, or similar. and heterogenous is when the substance is different. like gases, liquids, and solids. Hope that helps some.
Theory as to what will happen in the experiment. It is essentially an educated guess about what you expect the outcome of the experiment to be.
Answer:
CaCO3: 1 calcium 1 carbon 3 oxygen
CaO: 1 calcium 1 oxygen
CO2: 1 carbon 2 oxygen
