Answer:
1.2
Explanation:
Molarity = moles/volume
to find the moles, you must multiply both sides by volume
so, take 1.5 L * 0.80 M
this equals 1.2 :)
According to the law of conservation of mass, the mass of reactants will be equal to the mass of the products. The mass of products and reactants will only differ during a nuckear reaction
Changing of the physical state of water is not a nuclear reaction. So becoz of that the mass will remain constant without any change.
I think it's 2 I tried looking it up because I was not sure.
From 5 L to moles, just divide 5 by 22.4. I got 0.22 moles of H2.
From 5 moles to liters, just multiply 5 by 22.4. I got 112 L of H2.
