1374.75 is the concentration in milligrams per ml of a solution containing 23.5 meq sodium chloride per milliliter.
Concentration in chemistry is calculated by dividing a constituent's abundance by the mixture's total volume.
It is calculated in mg/ml.
The unit of measurement frequently used for electrolytes is the milliequivalent (mEq). This value compares an element's chemical activity, or combining power, to that of 1 mg of hydrogen.
Formula for calculating concentration in mg/ml is
Conc. (mg/ml) = M(eq) /ml × Molecular weight / Valency
Given
M(eq) NaCl/ ml = 23.5
Molecular weight pf NaCl = 58.5 g/mol
Valency = 1
Putting the values into the formula
Conc. (mg/ml) = 23.5 ×58.5/1
= 1374.75 mg/ml
Hence, 1374.75 is the concentration in milligrams per ml of a solution containing 23.5 meq sodium chloride per milliliter.

Answer:
The first molecule Avogadro constant is given as 6.022 X 10∧23/ mol
Explanation: Avogadro constant is the constituent particles of molecules, atoms and ions that make up a mole of an element or compound. Therefore, CO2 comprises one molecule, which is equivalent to 6.022 X 10∧23/ mol.
Answer:
C₇ H₁₆ + 11O₂ → 7CO₂ + 8H₂O
Explanation:
Given equation
C₇ H₁₆ + O₂ → CO₂ + H₂O
To solve this problem,
We use a mathematical approach to balance the equation:
aC₇ H₁₆ + bO₂ → cCO₂ + dH₂O
Conserving C; 7a = c
H ; 16a = 2d
O: 2b = 2c + d
Let a = 1
c = 7
d = 8
b = 11
Now insert the parameters and solve;
C₇ H₁₆ + 11O₂ → 7CO₂ + 8H₂O
The rate of growth is faster in the (10 - 14) age group and slows down after the age of 14. After the age of 16 the growth is the slowest
Respuesta:
2 m
Explicación:
Paso 1: Información provista
- Volumen inicial (V₁): 100 mL
- Concentración inicial (C₁): 4 m
- Volumen final (V₂): 200 mL
- Concentración final (C₂): ?
Paso 2: Calcular la concentración de la solución final
Queremos perparar una concentración diluida a partir de una concentrada. Podemos calcular la concentración de la solución diluida usando la regla de dilución.
C₁ × V₁ = C₂ × V₂
C₂ = C₁ × V₁ / V₂
C₂ = 4 m × 100 mL / 200 mL = 2 m
