<span>Density
is a value for mass, such as kg, divided by a value for volume, such as m3.
Density is a physical property of a substance that represents the mass of that
substance per unit volume. We calculate as follows:
Density = mass of gasoline/ volume of gasoline = (1</span>46.770 g -110.525 g ) / <span>50 ml = 0.7249 g/mL</span>
Answer:
The answer to your question is: P = 419933.5 Pa
Explanation:
Data
R = 0.287 KJ/Kg°K = 287 J/Kg°K
mass = 2 kg
T = 35 °C = 308°K
Container = 0.750 meters each side
Volume = l x l x l
= 0.750 x 0.750 x 0.750
= 0.421 m³
P = mRT / V
P = (2)(287)(308) / 0.421
P = 176792 / 0.421
P = 419933.5 Pa
Answer:
6.17 g/cm³
Explanation:
Data given:
one side of cube = 0.53 cm
mass of the cube is 0.92 g
density of the cube = ?
Solution:
First we will calculate for volume the cube
As we know all the sides or edges of a cube are equal so volume equation will be
So,
V = length x width x height
V = e³
as on side = 0.53 cm
then
V = (0.53 cm)³
V = 0.149 cm³
Now we will calculate density of cube
To calculate density, formula will be used
d = m/v . . . . . (1)
where
d = density
m = mass
v = volume
put values in above formula 1
d = 0.92 g / 0.149 cm³
d = 6.17 g/cm³
so. the density of cube = 6.17 g/cm³
You just need to convert it into moles per Liter (mol/L).
0.0815mol / 0.550L = 0.148mol/L
