What is the temperature of 0.750 mol of a gas stored in a 6,050 mL cylinder al 221 atm?
Rasek [7]

Answer:

T = 246 K

Explanation:

Given that,

Number of moles, n = 0.750 mol

The volume of the cylinder, V = 6850 mL = 6.85 L

Pressure of the gas, P = 2.21 atm

We need to find the temperature of the gas stored in the cylinder. We know that,

PV= nRT

Where

R is gas constant

T is temperature

So,

T=\dfrac{PV}{nR}\\\\T=\dfrac{2.21\times 6.85}{0.75\times 0.0821}\\T=245.85\ K

or

T = 246 K

So, the temperature of the gas is equal to 246 K.

If an object is travelling 25.0 meters/second, how far will it travel in 45 minutes?
Misha Larkins [42]
  • Speed=25m/s
  • Time=45min=(45×60)s=2700s

\\ \rm\longmapsto Distance=Speed(Time)

\\ \rm\longmapsto Distance=25(2700)

\\ \rm\longmapsto Distance=67500m

How many moles are there in 13g of KMnO4?
Hoochie [10]

Answer:

0.08 moles

Explanation:

Relative atomic mass of KMnO4 = K + Mn + O4 = 39 + 55 + 16 x 4 = 158

=> Moles in 13g of KMnO4 = \frac{Mass}{Relative-atomic-mass} = \frac{13}{158} = 0.082278.. = 0.08 moles
