B) 120 cg/mL , because 1g = 100cg and 1L = 1000mL

Answer:

B. 120 cg/ ml

Step-by-step explanation:

If a liquid has a density of 1,200 g/L, what is its density in cg/mL?

To fin this, we will simply use the idea of proportion. But first we need to know the number of gram per liter in 1 centigram per milliliter. Thus;

Let x = density of liquid in cg/ ml

1 cg/ml = 10 g/l

x = 1,200 g/l

cross- multiply

10x = 1,200

Divide both-side of the equation by 10 to get the value of x

10x/10 = 1,200/10

(At the left-hand side of the equation, 10 on the numerator will cancel-out 10 on the denomination and we will be left with just x, while on the right-hand side of the equation, 1200 will be divided by 1200)

x = 1,200/10

x =120 cg/ml

Therefore, the density of the liquid is 120 cg/ml
