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.

Find the volume of 200g of benzene, if the density of benzene is 0.88 g/mL.
Lina20 [59]

Answer:

<h2>227.27 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density} \\

From the question we have

volume =  \frac{200}{0.88}  \\  = 227.2727...

We have the final answer as

<h3>227.27 mL</h3>

Hope this helps you
