The concentration of protein in a urine sample is calculated to be 2.77 μg/mL. What is the concentration of this solution in uni

maxonik [38]

Answer:

The concentration of this solution in units of pounds per gallon is $2.776*10^{-5} \frac{lb}{gal}$

Explanation:

Units of measurement are established models for measuring different quantities. The conversion of units is the transformation of a quantity, expressed in a certain unit of measure, into an equivalent one, which may or may not be of the same system of units.

In this case, the conversion of units is carried out knowing that 1 μg are equal to 2.205*10⁻⁹ Lb and 1 mL equals 0.00022 Gallons. So

$2.77 \frac{ug}{mL} = \frac{2.77 ug}{mL}$

If 1 μg equals 2.205*10⁻⁹ lb, 2.77 μg how many lb equals?

$lb=\frac{2.77ug*2.205*10^{-9}lb }{1ug}$

lb=6.10785*10⁻⁹

So, 2.77 μg= 6.10785*10⁻⁹ lb

Then:

$2.77 \frac{ug}{mL} = \frac{2.77 ug}{mL}=\frac{6.10785*10^{-9}lb }{mL} =\frac{6.10785*10^{-9}lb }{0.00022 gal} =\frac{6.10785*10^{-9}lb }{0.00022 gal}$

You get:

$2.77 \frac{ug}{mL} = 2.776*10^{-5} \frac{lb}{gal}$

The concentration of this solution in units of pounds per gallon is $2.776*10^{-5} \frac{lb}{gal}$

Which of the answer choices correctly describes two liquids that cannot combine and form a homogeneous mixture?

tia_tia [17]

The term that is being described above is what we call IMMISCIBLE. This means when liquids are immiscible, it cannot be mixed in order to make a homogeneous mixture. When two liquids are mixed, these will eventually form layers. The answer to this is the first option. Hope this helps.

In which of the following species does sulfur have the same oxidation number as it does in H2SO4?(A) H2SO3

Dmitry_Shevchenko [17]

Answer:

Explanation:

To solve this question, we need to know the oxidation number in the compound in the question. The name of the compound is tetraoxosulphate(vi) acid. We can obviously see that the oxidation number of sulphur in this particular compound is 6.

A. Is wrong

The name of the compound is trioxosulphate(iv) ion

B. Is wrong

S2O32-

2S + 3(-2) = -2

S = +2

C.is wrong

Oxidation state there is -2

D is wrong

The oxidation number here is zero

E is correct

Oxidation number of oxygen is -2 and that of chlorine is -1

Hence:

S + 2(-2) + 2(-1) = 0

S -4 -2 = 0

S = 4+2 = +6
