From the explanation, we are given that:

  • The mole of gas n1 = 0.65 mol
  • The volume it occupied V1 = 900.0 ml
  • Mole of Neon = 0.35 ml
<h2>Further Explanation</h2>

To solve this question, we have to consider the Avogadro’s law, which state that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules”

Therefore, we have to calculate the total number of moles of the gases.

(0.65 + 0.35) mol

1.00 mol

Also we know that the volume it occupied V2 = unknown

According to the Avogadro’s law, the equation will be

0.65 mol x 900.0ml = 1.00ml x V2

585ml = 1.00 ml x v2

V2 = 585ml

To convert 585ml to litre, then we have to divide the derived value by 1000

Therefore we have

\frac{ 585ml}{1000}

0.6L

Therefore, the volume of gas in liters that syringe will hold if 0.35 moles of neon is added is 0.6L

<span>PV=nRT= a universal constant For any condition P1V1/n1T1=R and P2V2/n2T2=R i.e P1V1/n1T1=P2V2/n2T2 Becomes V1/n1=V2/n2 rearranging and solving V2=V1X(n2/n1)= 750 mLx((0.65+0.35)/(0.65))=1200ml=1.2L...2 sig figs</span>

calculate the number of moles of gas that occupy a 3.45L container at a pressure of 1.48 atm and a temperature of 45.6 Celsius ​
Otrada [13]

Answer:

There are 0,2 moles of gas that ocuppy the container.

Explanation:

We apply the formula of the ideal gases, we clear n (number of moles); we use the ideal gas constant R = 0.082 l atm / K mol. Firs we convert the unit of temperature in Celsius into Kelvin:

0°C= 273 K ------> 45,6 °C= 273 + 45, 6= 318, 6 K

PV= nRT ---> n= PV/RT

n= 1,48 atm x 3,45 L /0.082 l atm / K mol x 318,6 K

n= 0,195443479 mol
