Answer:
P₂ = 450 kiloPascals
Explanation:
Boyle's law :))
P₁V₁ = P₂V₂
300*75 = P₂*50
P₂*50= 300*75
P₂ = 300*75/50 = 450
P₂ = 450 kiloPascals

Fecl3 has a RFM of 56 + (35.5 * 3) = 162.5
so find out its moles 16.5 ÷ 162 5 = aprox. 0.1M
then there is a 1 : 3 ratio so 0.1 * 3 = 0.3
then times that by the avogado constant which is 6.02×10^23
0.3 × 6.02×10^23 = ans
hope that helps
Volume is the amount of space an object takes up
