When 3.00 moles of hydrogen molecules and 1.50 moles of oxygen molecules react, they form 3.00 moles of water When 3.00 moles of hydrogen molecules and 1.50 moles of oxygen molecules react, they form 3.00 moles of water
according to the reaction below.
2H2+ O2 + 2H2O
How many grams of oxygen were required?

2H, + O2 + 2H2O
How many grams of oxygen were required?

Mass of Oxygen required : 24 grams

Given

3 moles of H

1.5 moles of O

3 moles of H₂O

Required

Mass of O

Solution

Reaction

2H₂ + O₂ ⇒ 2H₂O

Mass of Oxygen for 1.5 moles of O :

= mol x Ar O

= 1.5 moles x 16 g/mol

= 24 grams

im not exactly sure but i think its b!

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
