Alex Ar [27]

Answer:

13.9atm

Explanation:

Use Boyle's Law: P1V1 = P2V2

Manipulate the equation: P2 = P1V1/V2

Substitute the values: P2 = (1.31atm)(5.51L)/0.520L

P2 = 13.88096atm

Optionally round to 3 sig figs to get 13.9atm

How many grams are in 4.63 x 1024<br><br> molecules of CCl4?
MrRa [10]

Answer:

m=1,182.8g

Explanation:

Hello!

In this case, since the relationship between molecules and mass is first analyzed via the Avogadro's number to compute the moles in the given molecules:

mol=4.63x10^{24}molec*\frac{1mol}{6.022x10^{23}molec}=7.69mol

We now use the molar mass of carbon tetrachloride (153.81 g/mol) to obtain the required grams:

m=7.69mol*\frac{153.81g}{1mol} \\\\m=1,182.8g

Best regards!
