The correct answer is a suspension.
A suspension is a mixture containing relatively large particles that settle fast
A homogenous mixture is a mixture where everything looks the same throughout and is all in the same phases
A colloid is a heterogenous mixture where the particles are small enough to stay suspended (usually talking about gaseous solutions)
And a solution is a homogenous mixture where the particles are too small to even reflect light
oxygen added to the copper is 3.300 grams.
<span>89.920 - 83.620 = 3.300 g oxygen </span>
<span>which is 0.2063 moles of oxygen. </span>
<span>3.300 g O x (1 mol O / 16.00 g O) = 0.20625 mol </span>
The mass of a sample of substance with a volume of 60.5 ml and a density of 1.20g/ml is 72.6 g.
Density, denoted as ρ, is a physical property of a material which is defined as the ratio between mass and volume or mass per unit volume. It is a measure of how much "stuff" or compact an object has in a unit volume. The more dense a substance is, the heavier it feels for its size.
To find the density, use the formula given by:
ρ = 
where
ρ = density
m = mass
v = volume
Using the same formula, we can transform it to solve for mass, if the volume and density are given.
ρ = 
m = ρv
Putting the values in,
m = 1.20g/ml x 60.5 ml
m = 72.6 g
Hence, the mass of a sample of substance with a volume of 60.5 ml and a density of 1.20g/ml is 72.6 g.
