n = m / M
m = n × M
Nitrogen (N2) - a gas is always with an index 2 if we don't have shown how many molecules are there
m (N2) = 4,5 mol × (2×14.007 g/mol)
m (N2) = 4,5 mol × 28.014 g/mol = 126.063g
if you don't solve with the decimals in class just replace 14.007 with 14
also if you haven't learned abour gasses aways having index 2 then:
m (N2) = 4,5 mol × 14.007 g/mol = 63.0315g
Answer:
a lot that's why it's really hot
Answer:
The atom having less atomic size.
Explanation:
Because the atom having less atomic size means having less atomic number are more close to nucleus so it having more attraction with respect to having large atomic size as it is far from the nucleus.
Answer:
your probably talking about atoms
