As the metal rusts it expands increasing its mass therefore increasing the weight.

Because the rusty nail had the combined mass of the original nail along with oxidized substances. since your adding something that exists to the  mass your mass will be greater.

The volume, in liters, occupied by 2.50 moles of N2 gas.<br><br><br> calculate at STP
kondaur [170]

Answer: The volume occupied by 2.50 moles of N_2 gas at STP is 56.0L

Explanation:

According to ideal gas equation:

PV=nRT

P = pressure of gas = 1 atm (at STP)

V = Volume of gas = ?

n = number of moles = 2.50

R = gas constant =0.0821Latm/Kmol

T =temperature =273K  (at STP)

V=\frac{nRT}{P}

V=\frac{2.50mol\times 0.0821Latm/K mol\times 273K}{1atm}=56.0L

Thus the volume occupied by 2.50 moles of N_2 gas at STP is 56.0L
