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

Answer:

B. 120 cg/ ml

Explanation:

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

<u><em /></u>

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

Are two atoms of the same element identical??​
Neko [114]
No. Although two such atoms are essentially chemically identical (they will chemically react in the same way), they are not completely identical.

Explain why the Chemicals properties of Mg 24 12 and Mg 26 12 are the same
Volgvan

Answer:

both Mg isotopes have same atomic number which is equal to number of protons , and the chemical properties of an element depends upon the the number of protons in its atom . and both Mg 24 12 and Mg 26 12 have same number of protons hence they exhibits similar chemical

What is the empirical formula for a compound if a sample contains 1. 0 g of S and 1. 5 g of O? SO SO3 S2O2 S2O3.
Tcecarenko [31]

The empirical formula of the given compound is \bold{SO_3}.

The correct option is B.

<h3>What is an empirical formula?</h3>

The empirical formula of a chemical compound is the simplest whole-number ratio of atoms contained in the substance.

Given,

1.0 g of S

1.5 g of O

To calculate the empirical formula, we will divide the masses of the elements by their atomic weight.

For sulfur

\bold{\dfrac{1.0}{32} =0.03125\; mol}

For oxygen

\bold{\dfrac{1.5}{16} =0.09375\; mol}

Now, divide the greater value of mole came by the smaller value

\bold{\dfrac{0.09375\; mol}{0.03125\;mol} = 3}

Thus, the empirical formula for the given compound is 1 for S and 3 for O

\bold{SO_3}

What is the molecular formula of a compound that has a molecular mass of 54 and the empirical formula is C2H3
iren [92.7K]
To find the molecular formula from the empirical formula, you need to find a multiple (x) that will give you the molar mass of the compound which in the question is 54 g/mol.

If C₂H₃ is the empirical formula
 molar mass of empirical formula = (12 × 2) + (1 × 3) g/mol
                                                     =  27 g/mol
let x = multiple
let molecular formula = C₂ₓ H₃ₓ

            multiple = molecular mass ÷ empirical mass
                         =  54 g/mol ÷  27 g/mol
                         =  2


If molecular formula = C₂ₓ H₃ₓ

then molecular formula = C₂₍₂₎H₃₍₂₎

                                      = <span>C₄H</span>₆
