How many moles are in 5.60 x 1027 molecules of carbon monoxide? with a bridge Please answer quickly I have to turn it in soon
OLEGan [10]

Answer:

9302 moles of CO contain 5.60×10²⁷ molecules

Explanation:

We solve this with Avogadro's number.

NA = 6.02×10²³

This number states the how many particles are in 1 mol of anything.

1 mol of atoms contains 6.02×10²³ atoms

1 mol of molecules  contains 6.02×10²³ molecules.

We apply a rule of three:

6.02×10²³ molecules are contained in 1 mol of CO

Then, 5.60×10²⁷ molecules may be contained in (5.60×10²⁷ . 1) / 6.02×10²³

= 9302 moles

Which law relates temperature, pressure, volume, and the number of moles of a gas under perfect conditions? Boyle's law Charles'
Triss [41]
<span>The correct answer is ideal gas law.

when the ideal gas law formula is:

 PV = nRT ,

when P is the pressure. 

V is the volume. 

and R is the ideal gas constant.

T is the temperature. 

and n is the number of moles.

So, this is the law which relates pressure, temperature, volume and number of moles . and this law state that 1 mole of an ideal gas will occupy a volume V = 22.4 L</span>
