Question

Find the mass/volume

3. D= 46.9 g/m^3
M= 47.14g
V= ?

4. D= 35 g/cm^3
M= ?
V= 47 cm^3

5. D= 22 kg/mm^3
M= ?
V= 1.89 mm^3​

Answer 1

To find the mass/volume in each case, we can use the formula:

Density (D) = Mass (M) / Volume (V)

For calculation:

3. Given D = 46.9 g/m^3 and M = 47.14g, we can rearrange the formula to solve for V:

V = M / D

= 47.14g / 46.9 g/m^3

≈ 1.005 m^3

4. Given D = 35 g/cm^3 and V = 47 cm^3, we can rearrange the formula to solve for M:

M = D * V

= 35 g/cm^3 * 47 cm^3

= 1645 g

5. Given D = 22 kg/mm^3 and V = 1.89 mm^3, we can rearrange the formula to solve for M:

M = D * V

= 22 kg/mm^3 * 1.89 mm^3

= 41.58 kg
