Mol = mass/ molar mass
So look up the molar mass of nitrogen on your periodic table, which is 14
But REMEMBER it's asking for nitrogen gas which is N2
So, molar mass= 2*14= 28 g/mol
mol= (14g)/ (28 g/mol)= 0.5 mol
So now you got your number of moles
at STP mol= volume/ 22.4 dm^3
so (0.5)(22.4)= 11.2 dm^3 which is 11.2 L
yo, just memorize them mole formulas and you'll be good fam-- just make sure to pay attention to STP or SATP, and if they're asking for "gas" or just the atom!
Depending on what you are using the chemical could react in an explosion if the substance is not known
Answer:
Pure sulfur is a tasteless, odourless, brittle solid that is pale yellow in colour, a poor conductor of electricity, and insoluble in water. It reacts with all metals except gold and platinum, forming sulfides; it also forms compounds with several nonmetallic elements.
Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature.
