An anesthetic gas contains 64.81% carbon, 13.60% hydrogen, and 21.59% oxygen, by mass. if 2.00 l of the gas at 25°c and 0.420 atm weighs 2.57g, what is the molecular formula of the anesthetic? enter the molecular formula in this order c#h#o# so c1h2o3 if an index is = 1, write it down

Most nonmetals are gases at room temperature

Explanation:

Nonmetals are moldable and easily shaped. Untrue,  non metals are brittle and normally break when one tries to mold or shape them

Most nonmetals are gases at room temperature. That is true. Examples include oxygen, nitrogen, carbon dioxide

Nonmetals fracture easily under pressure. Not true, again non metals are commonly brittle if they are in the solid state and therefore cannot withstand pressure without deforming

Most nonmetals are liquids at room temperature. Not true. the majority of none metals do not take the liquid state. They take gaseous and solid forms
