Answer:

<h3>The answer is 8.29 %</h3>

Explanation:

The percentage error of a certain measurement can be found by using the formula

$P(\%) = \frac{error}{actual \: \: number} \times 100\% \\$

From the question

actual density = 19.30g/L

error = 20.9 - 19.3 = 1.6

We have

$p(\%) = \frac{1.6}{19.3} \times 100 \\ = 8.290155440...$

We have the final answer as

Which of the following sets of empirícal formula, molar mass, and molecular formula is correct?

skad [1K]

<em>Answer:</em>

The option C is correct.
CH4N, 90g, C3H12N3.

<em>Explanation:</em>

<em>Option C:</em>

The molecular formula is C3H12N3.

If we take ratio 3:12:3 that will be equal to 1:4:1 so its empirical formula will be CH4N.
The molar mass of molecular formula = (12×3) + (1×12) +( 14×3) = 98 g

<em>Option A :</em>

In option A , molecular and empirical formula are both correct but molar mass is not valid. It should be 169 acc. to molecular formula.

<em>Option B:</em>

In option B, molecular formual is not valid.
It should be as C6H16O2
