Milk has a density of 1.04 g/ml. If you have a volume of 510 ml, what is the mass in grams

Law Incorporation [45]

Density is defined as the ratio of mass and volume. The formula of density is:

$density = \frac{mass}{volume}$ -(1)

Density of milk = $1.04 g/mL$ (given)

Volume of milk = $510 mL$ (given)

Substituting the values in formula (1):

$1.04 g/mL = \frac{mass}{510 mL}$

$mass= 1.04 g/mL \times 510 mL$

$mass = 530.4 g$

Hence, the mass of the milk is $530.4 g$ .

Ou have a 5 ml sample of a protein in 0.5 m nacl. you place the protein/salt sample inside dialysis tubing (see fig. 2-14) and p

Oduvanchick [21]

Answer:

Procedure (2)

Explanation:

Assume the dialyses come to equilibrium in the allotted times.

Procedure (1)

If you are dialyzing 5 mL of sample against 4 L of water, the concentration of NaCl will be decreased by a factor of

$\dfrac{5}{4000} = \dfrac{1}{800}$

Procedure (2)

For the first dialysis, the factor is

$\dfrac{5}{1000} = \dfrac{1}{200}$

After a second dialysis, the original concentration of NaCl will be reduced by a factor of

$\dfrac{1}{200} \times \dfrac{1}{200} = \dfrac{1}{40000}$

Procedure (2) is more efficient by a factor of

$\dfrac{40000}{800} = \mathbf{50}$
