Answer:
the density of lithium will be equal to: 0.582 g/cm^3
Explanation:
We have the following data:
a = 430 pm = 4.3x10^-8 cm
molar mass of lithium MM = 6.97 g/mol
Since the cubic cell of lithium is cubic centered in the face, its value of Z will be equal to 4
Avogadro´s number AN = 6.022x10^23 particles/mol
using the following formula we will calculate the density of lithium:
d = (Z*MM)/(a^3*AN) = (4*6.97)/((4.3x10^-8)^3*(6.022x10^23)) = 0.582 g/cm^3
Answer:
Explanation:
Divide the mass by the density and the units of grams will cancel so youll end up with mL.
(52.757g)/(12.5g/mL) = 4.2mL
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.
