How many kL does a 9.51 ´ 109 cL sample contain?
elena-14-01-66 [18.8K]

Answer:

9.51 × 10⁴ kL

Explanation:

Step 1: Given data

Volume of the sample (V): 9.51 × 10⁹ cL

Step 2: Convert "V" to liters

We will use the conversion factor 1 L = 100 cL.

9.51 × 10⁹ cL × (1 L / 100 cL) = 9.51 × 10⁷ L

Step 3: Convert "V" to kL

We will use the conversion factor 1 kL = 1000 L.

9.51 × 10⁷ L × (1 kL / 1000 L) = 9.51 × 10⁴ kL

9.51 × 10⁹ cL is equal to 9.51 × 10⁴ kL.

For which of the following molecular formulas is the formula shown in parentheses the correct empirical formula? (a) C12H22O11 (
Elodia [21]

Answer:

C₁₂H₂₂O₁₁ (C₁₂H₂₂O₁₁ ).

Explanation:

The empirical formula is obtained when we divide the molecular formula with a whole number giving the simplest ratio of all the elements (in whole number).

a) C₁₂H₂₂O₁₁ :

There is no number with which we can divide the ratio further to get a simpler formula hence the molecular formula of the given compound is the empirical formula of the compound. Hence it is correct.

(C₁₂H₂₂O₁₁),

(b) C₈H₁₂O₄

The empirical formula can be obtained by dividing the formula with "4"

The empirical formula would be

(C₂H₃O)

(c) H₂O₂

The empirical formula would be (H₁O₁)
