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!

2. How does systemic and pulmonary circulation differ from each another?
Kipish [7]

Explanation:

systemic and pulmonary circulation differ from each other because the pulmonary circulation is part of the circulatory system responsible for forming a circuit of vessels that transport blood between the heart and lungs, and systemic circulation, on the other hand, forms a closed circuit between the heart and the rest of the body.
