“¿CÓMO ENVIAR SUMINISTROS A ZONAS INACCESIBLES?”
Una empresa dedicada a la fabricación y distribución de insumos médicos está ensayando distintos diseños de paracaídas para atender su reparto de vacunas a lugares inaccesibles como pequeñas poblaciones asentadas en quebradas o en selva virgen donde no existen carreteras de acceso o pistas de aterrizaje. En este momento sus paracaídas se encuentran en la etapa de investigación y ensayos que permitan asegurar que una caja con las vacunas en frascos de vidrio no se dañe en el momento de llegar al suelo. Dentro de los parámetros de eficiencia que maneja la empresa fabricante de estos paracaídas para suministros, este debe ser pequeño, económico, ligero, resistente; pero en especial, debe reducir significativamente la velocidad de caída de una caja de tetrapak de 1 litro cuyo peso oscila entre los 45 g y 50 g, es decir, el tiempo de descenso con el paracaídas debe ser por lo menos el triple del tiempo de caída libre de la caja.
Para tu pregunta de indagación y su respectiva hipótesis de trabajo, distribuye tus variables en el siguiente cuadro:
Variable Independiente (V. I): Causa
Variable Dependiente (V.D): Efecto
Variables intervinientes (Por controlar para que no afecte a la variable dependiente)

Ответ:
The percentage by volume of Oxygen gas in the Trimex blend is 28.2%.
Explanation:
We shall use the formula that connects the mole ratio of a particular gas in a mixture with the partial pressure of that gas and the total pressure of the mixture: which is:
Mole ratio of Oxygen in Trimex = Partial pressure of Oxygen in Trimex divided by the Total pressure of all the gases that made up of Trimex.
Here we go, mole ratio of Oxygen= 55/195. The total pressure is the addition of the partial pressures of all the gases in the Trimex mixture, which is 55+90+50=195.
So the mole ratio of our Oxygen gas will be: 0.282, no unit.
This means we can assume the total moles of all the gas is 1, and oxygen is 0.282.
Since we know that 1 mole of any gas will have 22.4dm cube as volume, then the total volume of the Trimex will be 22.4dm cube, while that of the oxygen gas will be 0.282 X 22.4 dm cube= 6.3179dm cube. Therefore, the percentage by volume of Oxygen gas in the Trimex will be: 6.3179/22.4 X 100 = 28.2%.
