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}

<u><em>The concentration of this solution in units of pounds per gallon is </em></u>2.776*10^{-5} \frac{lb}{gal}<u><em></em></u>

Consider the reaction: Mg(OH)₂ (s) ⇌ Mg²⁺ (aq) + 2 OH⁻ (aq)
balandron [24]

The value of Kc for the equilibrium is 0.150 mole² / litre ²

<u>Explanation:</u>

<u>Given:</u>

An equilibrium mixture in an 1.00 L vessel contains 5.30 moles of  

Mg(OH )₂  0.800 moles of Mg²⁺ and 0.0010 moles OH₋  

We have to find the value of Kc

  • Step 1: Find  the equilibrium Concentration.
  • Step 2: Substitute the values in the equation.
  • Step 3: Find the value of Kc.
  • I have attached the document for the detailed explanation

The value of Kc for the equilibrium is 0.150 mole² / litre ²
