30 its ASAP!!!! What is the volume, in liters, occupied by 0.485 moles of Oxygen gas at 23.0 oC and 0.980 atm?
USPshnik [31]
Use the universal gas formula

PV=nRT
where
P=pressure ( 0.980 atm)
V=volume (L)
T=temperature ( 23 ° C = 23+273.15 = 296.15 ° K)
n=number of moles of ideal gas (0.485 mol)
R=universal gas constant = <span>0.08205 L atm / (mol·K)

Substitute values,
Volume, V (in litres)
=nRT/P
=0.485*0.08205*296.15/0.980
= 12.0256 L
= 12.0 L (to three significant figures)

Explain why the statement “The speed of light is 300 million m/s” is not always correct.
levacccp [35]

Because the speed of light is determined by the medium that is it in. If light is in a vacuum it goes 300 million meters per second but it is slower in air, and even slower in water because water is more dense than the previous two.

A reaction produces 0.801 moles of H2O. How many molecules of H20 are produced?
timama [110]

Answer:

1 mole of molecules = 6.022 × 10²³ molecules

1 = 6.022 × 10²³ molecules / mole

Multiplying a number with [6.022 × 10²³ molecules / mole] is like multiplying the number with 1 so  0.877 mole × 6.022 × 10²³ molecules / mole = 5.28 × 10²³ molecules

5.28 × 10²³ molecules of water is produced.
