Answer:
14g
Explanation:
assuming that N2 is a gas, use the gas formula ( mole = volume/24) to find the number of moles
then once you have found the moles (0.5 mol) use the (mole = mass/mr) formula to find the mass
so, 0.5 x 28 = 14g

Answer:
The element with electron configuration 1s² 2s² 2p⁶ will most likely not........

• </span>Volume of the marshmallow:
V = 2.75 in^3 (but, 1 in^3 = 16.39 cm^3)
V = 2.75 × 16.39 cm^3
V = 2.75 × 16.39 cm^3
V = 45.0725 cm^3
• Density:
d = 0.242 g/cm^3
<span>• </span>Mass:
m = d × V
m = (0.242 g/cm^3) × (45.0725 cm^3)
m = (0.242 g/cm^3) × (45.0725 cm^3)
m = 10.907545 g
m ≈ 10.9 g <——<span>— this is the answer.
I hope this helps. =)
