We can use the combined gas law equation to find the new temperature 
\frac{P1V1}{T1} =  \frac{P2V2}{T2}
parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation 
P - pressure 
P1 - 0.925 atm x 101 325 Pa/atm = 93 726 Pa
P2 - 625 torr x 133 Pa/torr = 83 125 Pa
V - volume 
V1 - 10.1 L
V2 - 12.2 L
T - temperature in kelvin
T1 -  25 °C + 273 = 298 K
substituting these values in the equation
\frac{93726Pa * 10.1L }{298K} =  \frac{83125 Pa*12.2L}{T2}
T = 319 K
temperature in celsius - 319 K - 273 = 46 °C

How many liters will 2.76 mol CO2 occupy?<br> 2.76 mol<br> II
sergeinik [125]

This problem is providing information about the moles of carbon dioxide, 2.76 mol, and asks for the volume this amount takes up, turning out to be 61.8 L according to the Avogadro's law:

<h3>Avogadro's law:</h3><h3 />

In chemistry, gas laws are used to relate the behavior of gases by virtue of the their pressure, volume, temperature and moles; thus several gas laws exist for us to do so, however, we here focus on the Avogadro's law which relates the volume and moles when both temperature and pressure are held constant.

In such a way, since no information on the constant variables is given, we assume the mentioned carbon dioxide is at STP, (0 °C and 1 atm), which means that we can use the following equivalence statement derived from the ideal gas law (PV=nRT):

22.4 L = 1 mol

Hence, we calculate the required volume:

2.76molCO_2*\frac{22.4L\ CO_2}{1molCO_2} =61.8L\ CO_2

How many electrons are in an atom with the electron<br> configuration of 1s 2s 2p 3s!?
Viefleur [7K]

Answer:

11

Explanation:

electronic configuration = 1s^2, 2s^2, 2p^6, 3s^1

therefore total electrons = 2+2+6+1 = 11
