Answer:
25.04 g is the mass of pentane
Explanation:
Pentane density = Pentane mass / Pentane volume
1 cm³ = 1mL
0.626 g/mL = Pentane mass / Pentane volume
0.626 g/mL = Pentane mass / 40 mL
0.626 g/mL . 40 mL = Pentane mass → 25.04 g
Molar mass:
KOH = 56.0 g/mol
Number of moles of KOH :
5.93 / 36.5 => 0.1624 moles
<span>KOH + HCl = KCl + H₂O
</span>
1 mole KOH --------------> 1 mole HCl
0.1624 moles KOH ----> ?
moles HCl = 0.1624 x 1 / 1
= 0.1624 moles of HCl
V ( HCl ) = moles / molarity
V(HCl) = 0.1624 / 0.183
V (HCl) = 0.887 L x 1000 = 887 mL
