Creatinine, �!�!�!�, is a by-product of muscle metabolism, and creatinine levels in the body are known to be a fairly reliable i
Inessa05 [86]

Answer:

Explanation:

molecular weight of creatinine = 131

1 mg of creatinine = 1 x 10⁻³ / 131 = 7.63 x 10⁻⁶ mole of creatinine.

volume of solution = .1 L

mass of blood solution = .1 x 1025

= 102.5 g

mass of solvent = 102.5 g approximately

= .1025 kg

molality = mole of solute / mass of solvent in kg

= 7.63 x 10⁻⁶ / .1025 kg

= 74.44 x 10⁻⁶ .

Osmotic pressure :---

π V / T = nR     π is  osmotic pressure , V is volume of solution in liter , T is absolute temperature , n is molality .

π x .1 / 298 =  74.44 x 10⁻⁶ x .082

π = 18.19 x 10⁻³ atm

Drag the labels onto the table to indicate when each statement Is true. Labels can be used once, more than once, or not at all.
liq [111]

The labels the table to indicate when each statement Is true. Labels can be used once, more than once, or not at all, The orange dye moves independently of the purple dye. 2. Concentration gradients exist that drive diffusion of both dyes. : <u>free water, solute, free water, solute.</u>

In chemistry, attention is the abundance of a constituent divided by way of the total quantity of an aggregate. several types of mathematical descriptions may be prominent: mass concentration, molar concentration, range concentration, and quantity concentration.

it's miles the amount of solute dissolves in one hundred g solvent. If the attention of the answer is 20 %, we understand that there are 20 g solutes in one hundred g solution. instance: 10 g salt and 70 g water are mixed and the solution is ready. find awareness of the answer by means of percentage mass.

0.632 mole of carbon dioxide is produced in a chemical reaction at STP. What
levacccp [35]

Answer:

V = 14.2 L

Explanation:

Given data:

Moles of CO₂ = 0.632 mol

Temperature = standard = 273 K

Pressure = standard = 1 atm

Volume of gas = ?

Solution;

Formula:

PV = nRT

R = general gas constant = 0.0821 atm.L/ mol.K

Now we will put the values in formula.

V = nRT/P

V = 0.632 mol ×0.0821 atm.L/ mol.K × 273 K / 1 atm

V = 14.2 L/ 1

V = 14.2 L
