The density of pure solid copper is 8.94 g/cm3. What volume does 5.0 kilograms of copper occupy? Leave your answer in the approp

azamat

We have that the volume that 5.0 kilograms of copper occupy is

V=0.001788cm^3

From the question we are told

The density of pure solid copper is 8.94 g/cm3.

volume does 5.0 kilograms of copper occupy

Generally the equation for the Density is mathematically given as

$\rho=\frac{m}{V}\\\\Therefore\\\\V=\frac{m}{\rho}\\\\V=\frac{8.94}{5.0*1000}$

V=0.001788cm^3

Therefore

the volume that 5.0 kilograms of copper occupy is

V=0.001788cm^3

In conclusion

The volume that 5.0 kilograms of copper occupy is

V=0.001788cm^3

nlexa [21]

Answer:

7.5 m/s^2

Explanation:

v=at

a= v/t

Since you have to v so

(v2- v1) /t

(15-0)/2= - 7.5

What is the relashinship between the mass and size of a planet?

Snowcat [4.5K]

Size is in relation to distance(how far across or around)mass is measuring how much there is, mass is related to both size and DENSITY, EX: A balloon has a large size but a tiny mass, compared to a bowling ball, which has a similar size but a much larger mass

What is the specific heat (J/g⋅∘C) of a metal object whose temperature increases by 3.0∘C when 17.5 g of metal was heated with 3

lesya692 [45]

Answer:

0.733J/g°C

Explanation:

Using the formula

Q=mcΔθ

Q=38.5J, c=? , m=17.5g , Δθ=3°C

c= Q/(mΔθ)

$c=\frac{38.5}{17.5*3}$

c=0.733J/g°C
