A balloon can be inflated with 4.23 Liters of O2gas at STP. How much will the balloon weigh in grams?

6.04 g

Explanation: In STP conditions, amoint of substance

n = V / Vm = 4.23 l / 22.41 l/mol = 0.188755 mol

Molar mass M(O2) = 32 g/mol  and

mass m = nM

sorry idk the answer well to you i have a explaination

explanation: a formula which shows the arrangement of atoms in the molecule of a compound

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
