according to Boyles law if the initial pressure and volume of a gas were five atm for the pressure and 10 mL for the volume and

maks197457 [2]

Answer:The new volume is 5mL

Explanation:

The formular for Boyles Law is; P1 V1 = P2 V2

Where P1 = 1st Pressure V1 = First Volume

P2 = 2nd Pressure V2 = Second Volume

From the question; P1 = 5atm, V1 = 10ml

P2 = 2 x P1 (2 x 5) = 10 atm V2 =?

Using the Boyles Law Formular; P1 V1 = P2 V2, we make V2 the subject of formular; P1 V1/ P2 = V2

∴ 5 x 10/ 10 = 5

∴ V2 = 5mL

What volume in litres will 38gr of F2 occupy at 0.999 bar and 273 K

Oliga [24]

Answer:

$V=22.68L$

Explanation:

Hello,

In this case, we use the ideal gas equation to compute the volume as shown below:

$PV=nRT\\\\V=\frac{nRT}{P}$

Nonetheless we are given mass, for that reason we must compute the moles of gaseous fluorine (molar mass: 38 g/mol) as shown below:

$n=38 g *\frac{x}{y} \frac{1mol}{38 g} =1mol$

Thus, we compute the volume with the proper ideal gas constant, R:

$V=\frac{1mol*0.083\frac{bar*L}{mol*K}*273K}{0.999bar} \\\\V=22.68L$

Best regards.
