Carbon monoxide is a gas at 0 °c and a pressure of 1.58 × 105 pa. it is a diatomic gas, each of its molecules consisting of one

carbon atom (atomic mass = 12.0 u) and one oxygen atom (atomic mass = 16.0 u). assuming that carbon monoxide is an ideal gas, calculate its density ρ.

Given temperature = 0^{0}C = (0^{0} + 273 )K  = 273 K

Pressure = 1.58 ×10^{5} Pa ×\frac{1 atm}{1.01325*10^{5}Pa}

= 1.56 atm

Density =\frac{PM}{RT}

ρ = \frac{(1.56 atm)(28.01 g/mol)}{(0.08206 L.atm/mol.K)(273 K)}

= 1.95 g/L

<h3> The supplements that are minerals are</h3>
  1. calcium
  2. sodium
  3. iron
  4. zinc

<u><em> Explanation</em></u>

  • calcium   and sodium  are major  minerals   which are required  by the body for

      calcium-  needed  for muscle,hearing bone and  for the support of synthesis and function of cells

     sodium-   is needed to control blood  pressure  and  also for proper  muscle and nerve  function

  • Zinc  and iron are  required   in trace and both are needed for good health

You have 0.5 L of air at 203 k in an expandable container at constant pressure. You heat the container to 273 k. What is the vol
Jobisdone [24]
You can use P1V1/T1 = P2V2/T2 but since pressure is constant is becomes V1/T1=V2/T2

V1=0.5 L
T1=203 K
T2=273 K
V2=unknown

0.5L/203 = V2/273
V2= 0.67 L so C

Hope this helps :)

Un globo lleno de helio tenia un volumen de 8.5 L en el suelo a 20°C y a una presión de 750 torr. Cuando se le soltó, el globo s
Ray Of Light [21]

Answer:

El volumen del gas era 12.95 L

Explanation:

Se relaciona la presión y el volumen mediante la ley de Boyle, que dice:

“El volumen ocupado por una determinada masa gaseosa a temperatura constante, es inversamente proporcional a la presión”

La ley de Boyle se expresa matemáticamente como:  P*V=k

Por otro lado, la Ley de Charles consiste en la relación que existe entre el volumen y la temperatura absoluta de una cierta cantidad de gas ideal, el cual se mantiene a una presión constante. Esta ley dice que cuando la cantidad de gas y de presión se mantienen constantes, el cociente que existe entre el volumen y la temperatura siempre tendrán el mismo valor:  

\frac{V}{T}=k

Por último, la Ley de Gay Lussac dice que la temperatura absoluta y la presión son directamente proporcionales. Es decir, cuando se mantiene todo lo demás constante, mientras suba la temperatura de un gas subirá también su presión. Y mientras la temperatura del gas baje, lo mismo ocurrirá con la presión:

\frac{P}{T}=k

Combinado las mencionadas tres leyes se obtiene:

\frac{P*V}{T} =k

Cuando se desean estudiar dos diferentes estados, uno inicial y una final de un gas, se puede aplicar:

\frac{P1*V1}{T1} =\frac{P2*V2}{T2}

Recordando que la temperatura debe usarse en grados Kelvin, conoces los siguientes datos:

  • P1: 750 torr
  • V1: 8.5 L
  • T1: 20°C= 293°K (siendo 0°C=273°K)
  • P2: 425 torr
  • V2: ?
  • T2: -20°C= 253 °K

Reemplazando:

\frac{750 torr*8.5 L}{293K} =\frac{425 torr*V2}{253 K}

Resolviendo:

V2=\frac{750 torr*8.5 L}{293K} *\frac{253 K}{425 torr}

V2= 12.95 L

<u><em>El volumen del gas era 12.95 L</em></u>

A plant fertilizer contains 15% by mass nitrogen (N). In a container of soluble plant food, there are 12.2 oz of fertilizer. How
ale4655 [162]
51.86 grams would be in the container.

One ounce is an equivalent of 28.34 grams, so times that by 12.2
.
12.2 * 28.34 = 345.75.

Put the percentage into decimal form, so 15% would now be 0.15.

0.15 * 345.75 = 51.86.
