Calculate the masses.
(a) What is the mas of 4.00 cm3 of sodium, density = 0.97 g/cm?
(b) What is the mass of 125 mL gaseous chlorine, density = 3.16 g/L?

Respuesta :

Answer:

a) Mass = 3.9 g

b) Mass = 0.395 g

Explanation:

Density is related to the mass and volume of a substance by the relation:

[tex]Density = \frac{Mass}{Volume}----(1)[/tex]

a) Given:

Volume  = 4.00cm3

Density = 0.97 g/cm3

Based on equation (1)

[tex]Mass = density*volume = 0.97 g/cm3*4.00 cm3 =3.9 g[/tex]

b) Given:

Volume  = 125 ml

Density = 3.16 g/L

1 ml = 0.001 L

Therefore, 125 ml = 0.125 L

Based on equation (1)

[tex]Mass = density*volume = 3.16 g/L*0.125L =0.395 g[/tex]
