Determina la masa molar y el volumen que ocupa la siguiente sustancia CO2, si su masa es de 28 gr. *
balandron [24]

Answer:

Para el CO₂ sabemos que:

densidad = 0,001976 g/cm³

Sabemos que:

densidad = masa/volumen

Entonces, si tenemos una masa de 28 g, podemos escribir:

volumen = masa/densidad

volumen = (28g)/(0,001976 g/cm³) = 14,170 cm^3

Para obtener la masa molar (es decir, la masa de un mol de esta sustancia) simplemente sumamos la masa de un mol de cada componente.

Carbono: tiene una masa molar de 12 g/mol

Oxígeno: tiene una masa molar de 16 g/mol (y tenemos dos oxígenos)

entonces la masa molar va a ser:

masa molar = 12g/mol + 2*16g/mol = 44 g/mol

Es decir, un mol de CO₂, pesa 44 gramos.

Use the graph to find the x-intercept for the equation y + 2 = 2(x + 3).
Assoli18 [71]

Answer:

The x-intercept is 2

Step-by-step explanation:

So what you would do is you would distribute the 2 to x and 3 to get the equation y+2=2x+6. Then you would subtract 2 from both sides and get y=2x+4. And because your m is your x-intercept you get the answer: 2.

Simplify the expression. (3 points) -5+i/2i<br><br> WILL GIVE BRAINLY
Verizon [17]
\bf recall~that\qquad i^2=-1\\\\&#10;-------------------------------\\\\&#10;\cfrac{-5+i}{2i}\cdot \cfrac{i}{i}\implies \cfrac{i(-5+i)}{2i^2}\implies \cfrac{-5i+i^2}{2(-1)}\implies \cfrac{-5i+(-1)}{-2}&#10;\\\\\\&#10;\cfrac{-5i-1}{-2}\implies \cfrac{1+5i}{2}
