1 x 10 - 15 / 4.2 x 10 - 7

Due to order of operations you have to do do the multiplication and division first, from left to right.

So start with 1.0 x 10. This = 10.
Then you have to skip over the subtraction for now. Multiply 15 by 4.2. This equals 63. Then multiply this by 10, so 630.

Then rewrite the equation. It's 10 - 630 - 7. Then just subtract. 10 - 630 = -620.
-620 - 7 = -627. (Two subtracts make an add)

-627 is your answer

Svetach [21]

Answer:

V_2=36.84L

Explanation:

Hola,

En este caso, podemos usar la ley de Boyle, la cual nos permite analizar el comportamiento volumen-presión en un gas ideal de manera inversamente propocional:

P_1V_1=P_2V_2

Así, dado el volumen y la presión inicial, la cual se convierte a atmósferas (760 torr = 1atm), calculamos el volumen final a 1 atm como se muestra a continuación:

V_2=\frac{P_1V_1}{P_2}=\frac{700torr*\frac{1atm}{760torr}*40l }{1atm}\\  \\V_2=36.84L

Saludos!
