The sum of the </span>oxidation numbers<span> in a polyatomic ion is equal to the charge of the ion.</span>
Answer:
v = 4.62 L
Explanation:
Necessary Conversion:
1000 g = 1 kg
Density of Oil in kg/mL:
0.78g/ml * (1 kg/1000 mL) = 0.00078 kg/mL
Density Equation (Heart with an arrow through it):
d = m/v
Rewrite to Find Volume (Multiply Both Sides by v/d):
v = m/d
Substitue m and d to Find v:
v = (3.6 kg)/(0.00078 kg/mL)
v = 4615.38 mL
Convert to More Suitable Units (Liters) by Dividing by 1000:
v = 4.62 L
