: calculate the mass of the solute in 1.500 l of 0.30 m glucose, c6h12o6, used for intravenous injection

vfiekz [6]

Answer is: the mass of the glucose is 81,07 grams.
c(C₆H₁₂O₆) = 0,3 M = 0,3 mol/L.
V(C₆H₁₂O₆) = 1,500 L.
n(C₆H₁₂O₆) = c(C₆H₁₂O₆) · V(C₆H₁₂O₆).
n(C₆H₁₂O₆) = 0,3 mol/L · 1,5 L.
n(C₆H₁₂O₆) = 0,45 mol.
m(C₆H₁₂O₆) = n(C₆H₁₂O₆) · M(C₆H₁₂O₆).
m(C₆H₁₂O₆) = 0,45 mol · 180,156 g/mol.
m(C₆H₁₂O₆) = 81,07 g.

What is Alkali metals

seropon [69]

Answer:

The alkali metals consist of the chemical elements lithium, sodium, potassium, rubidium, caesium, and francium. Together with hydrogen, they constitute group 1, which lies in the s-block of the periodic table

The alkali metals are all shiny, soft, highly reactive metals at standard temperature and pressure and readily lose their outermost electron to form cations with charge +1.

1. The structural unit of nucleic acids are composed of repeating units of monomers called nucleotides. Nucelotides are composed of three functional groups: sugars which are specifically pentoses (5-Carbon sugars), phosphate group and nitrogenous base.

2. The two major classes of nucleic acids in the body are the DNA or deoxyribonucleic acids and RNA or ribonucleic acids.

3.
a. Based on the nitrogenous bases and sugar, the DNA has a deoxyribose as the sugar and its 4 bases are adenine, guanine, cytosine and thymine. For RNA, the sugar is ribose while its 4 bases are adenine, guanine, cytosine, and uracil

b. Based on the general three-dimensional structure, DNA is a double stranded β-helix with a long chain of nucleotides. RNA is composed of a shorter chain with a single strand α-helix structure.

c. Based on relative functions, the DNA is responsible for storing the genetic information while the RNA is responsible for transporting the genetic information to the ribosomes which synthesize proteins.

Genrish500 [490]

Answer:

The heat released is 56.7 kJ.

Explanation:

To solve this problem, first we need to find out the standard enthalpy of reaction, that is, the energy released at constant pressure in standard conditions (P=1bar, T=298.15K). We can find it using the expression:

ΔH°r = Σn(p).ΔH°f(p) - Σn(r).ΔH°f(r)

where,

n refers to the number of moles of reactants and products in the balanced equation

ΔH°f refers to standard enthalpies of formation (which can be found in tables).

Given the equation:

2 H₂O₂(l) → 2 H₂O(g) + O₂(g)

We can replace with the proper data in the equation:

ΔH°r = Σn(p).ΔH°f(p) - Σn(r).ΔH°f(r)

ΔH°r= [2 mol . ΔH°f H₂O(g) + 1 mol . ΔH°f O₂(g)] - [2 mol . ΔH°f H₂O₂(l)]

ΔH°r= [2 mol . (-241.8 kJ/mol) + 1 mol . 0 kJ/mol] - [2 mol . (-187.8 kJ/mol)]

ΔH°r = -108.0 kJ

Since enthalpy is an extensive property, it depends on the amount of reagents. In this case, 108.0 kJ of heat are released every 2 moles of H₂O₂(l) decomposed. Then, for 1.05 mol of H₂O₂(l):

$1.05 mol.\frac{-108.0kJ}{2mol} =-56.7kJ$

By convention, the negative sign means that heat is released.
