<span>After 6 days, only 4 grams of the original amount will remain after 6
days. I have attached an image on how to calculate half-life so you can plug
your give value into the formula.
</span><span>
To add, </span>half-life means for<span> a substance decaying exponentially, the amount of time it takes for the
amount of the substance to diminish by </span>half.
Two mixtures not combined , separated.<span />
Answer is: 127 <span>grams of metallic copper
</span>Chemical reaction: 2Al + 3CuSO₄ → Al₂(SO₄)₃ + 3Cu.
m(Al) = 54 g.
m(CuSO₄) = 319 g.
m(Cu) = ?
n(Al) = 54 g ÷ 27 g/mol
n(Al) = 2 mol.
n(CuSO₄) = 319 g ÷159,5 g/mol.
n(CuSO₄) = 2 mol, limiting reagens.
from reaction n(CuSO₄) : n(Cu) = 3 : 3 (1 : 1).
n(Cu) = 2 mol.
m(Cu) = 2 mol · 63,5 g/mol.
m(Cu) = 127 g.
