Missing: 643.21 ‎ Must include: 643.21. A balloon is filled with 36.2 liters of Cl2 gas at STP. How many moles of chlorine gas are inside? Solution: 36.2

Missing: 4.061 ‎Must include: 4.061 .For H2O, there is one atom of oxygen and two atoms of hydrogen. A molecule can be made of only one type of atom. In its stable molecular form, oxygen exists as two atoms and is written O2. to distinguish it from an atom of oxygen molecule of three oxygen atoms, in grams per mole or search for a chemical ... Did you mean to find the molecular weight of one of these similar formulas- 80.34.

Explanation: PLEASE MARK ME AS BRAINLIEST!

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
