Answer :
"cg" is centigram, which is one-hundredth of a gram.
I will first convert from g to cg (multiply by 100), then from mL to L (multiply by 1000).
[tex] \frac{0.55g}{mL}*\frac{100cg}{1g}*\frac{1000mL}{1L}=55,000\frac{cg}{L} \ or \ 5.5e4\frac{cg}{L} [/tex]
Density has been the ratio of the mass and the volume. It is denoted as D or ρ. An object with density of 0.55 g/mL converted is 55000 cg/L. Thus, option D is correct.
What is density?
Density is the physical property that has been estimated by dividing the mass and volume. The density of the substance or the matter tells about the compactness of the mass in a specified volume.
The density can be calculated in kilogram per cubic meter (kg/m³), grams per milliliter, or even in centigram per liter.
From the conversion table, it is known that,
1 gram = 100 centimeter gram
So, 0.55 grams = 55 centimeter grams
Also,
1 liter = 1000 mL
So, X liter = 55 mL
Solving for X:
55 mL × 1 L ÷ 1000 mL
X = 55000 L
The density in 0.55 g/mL will be converted to cg/L as, 55000 cg/L or 5.5 × 10⁴ cg/L.
Therefore, in option D. the density is 5.5 × 10⁴ cg/L or 55000 cg/L.
