Answer:
The answer to your question is None of your answers is correct, maybe the data are wrong.
Explanation:
Data
Concentration 1 = C1 = 1 M
Volume 2 = 5 ml
Concentration 2 = 0.05 M
Volume 1 = x
To solve this problem use the dilution formula
Concentration 1 x Volume 1 = Concentration 2 x Volume 2
Solve for Volume 1
Volume 1 = (Concentration 2 x Volume 2)/ Concentration 1
Substitution
Volume 1 = (0.05 x 5) / 1
Simplification
Volume 1 = 0.25/1
Result
Volume 1 = 0.25 ml
Answer:
Mathematics
Explanation:
Scientists in their own way use different types of statistics. As a child I went to a scientist lab and it was huge they had microscopes, animals in glass boxes, they use math to try to figure things out.
The buoyancy of an object is dictated by its density. So let us calculate for density, where:density = mass / volume
Calculate the volume first of a solid cube:volume = (6 cm)^3 = 216 cm^3 = 216 mL
Therefore density is:density = 270 g / 216 mLdensity = 1.25 g / mL
Therefore this object will float in the layer in which the density is more than 1.25 g / mL.
Answer:
2.7g/cm³
Explanation:
Given parameters:
Dimension of the aluminum = 10.5cm x 10.5cm x 0.1cm
Mass of the aluminum = 29.8g
Unknown:
Density = ?
Solution:
Density of a substance is its mass per unit volume;
Mathematically;
Density =
Volume of the aluminum = 10.5cm x 10.5cm x 0.1cm = 11.025cm³
So, insert the parameters and solve;
Density =
= 2.7g/cm³
