94.63 mg/L as a unit of density is equivalent to 9.463 × 10-⁵ g/mL.
<h3>What is density?</h3>
Density is a measure of the mass of matter contained by a unit volume.
Density of a substance can be calculated by dividing the mass of the substance in grams by its volume in milllilitres. This means that the unit of measurement for density is g/mL.
However, the conversion factor of g/mL to mg/L is as follows:
1 gram/millilitre = 1000000 milligrams/litre
94.63 mg/L = 94.63 ÷ 1000000
= 9.463 × 10-⁵ g/mL
Therefore, 94.63 mg/L as a unit of density is equivalent to 9.463 × 10-⁵ g/mL.

Answer:
The halogen bulb lasts longer because the filament lasts longer. It can have twice the life of an incandescent and use the same amount or slightly less (10%) electricity.
Explanation:
The calculated molar volume would decrease as CO2 would escape
t1/2 = ln 2 / λ = 0.693 / λ
Where t1/2 is the half life of the element and λ is decay constant.
32 = 0.693 / λ
λ = 0.693 / 32 (1)
Nt = Nο eΛ(-λt) (2)
Where Nt is atoms at t time, λ is decay constant and t is the time taken.
t = 1.9 hours = 1.9 x 60 min
From (1) and (2),
Nt = Nο e⁻Λ(0.693/32)*1.9*60
Nt = 0.085Nο
Percentage = (Nt/Nο) x 100%
= (0.085Nο/Nο) x 100%
= 8.5%
Hence, Percentage of remaining atoms with the original sample is 8.5%
