A sample of gas has a volume of 526 mL at 346 mmHg and 35.0°C. Determine the moles of gas.​
Furkat [3]

Answer:

The moles of gas is 0.009474 moles.

Explanation:

Given that,

Volume = 526 mL

Pressure = 346 mmHg

Temperature = 35.0°C

We need to calculate the moles of gas

Using formula of ideal gas

n=\dfrac{PV}{RT}

Where, P = pressure

V = volume

R = gas constant

T = temperature

Put the value into the formula

n=\dfrac{\dfrac{346}{760}\times0.526}{0.08206\times(35+273)}

n=0.009474\ moles

Hence, The moles of gas is 0.009474 moles.

What are 2 ways that convection currents in the oceans distribute the sun's energy?
dezoksy [38]

Answer:

When air in contact with the ocean is at a different temperature than the sea surface, heat transfer by conduction takes place. The ocean also absorbs and stores energy from the sun, and when precipitation falls, it releases heat energy into the atmosphere.

Hope it helps:)
