Calculate the density of a piece of wood, in the units of g/mL, with a volume of 2.5L and a mass of 12.5 kg
Ganezh [65]

Answer:

5 g / ml

Explanation:

Convert the values given to   g   and ml

12.5 kg = 12500 g

2.5 L = 2500 ml

12500 g / 2500 ml = 5 g/ml

mina [271]

C₂H₆O is referred to the chemical formula corresponds to this structural formula and is denoted as option D.

<h3>What is Chemical formula?</h3>

This contains information about the chemical proportion of atoms present in a molecule.

In this scenario, there are two carbon atoms, six hydrogen atoms and one oxygen atom which can be written as C₂H₆O. This is therefore the most appropriate choice in this scenario.

What is the empirical formula of a compound containing 5.03 grams carbon, 0.42 grams hydrogen, and 44.5 grams chlorine?
djverab [1.8K]

The empirical formula of the compound is CHCl₃.

<h3>Calculation:</h3>

Given,

Mass of carbon = 5.03 g

Mass of hydrogen = 0.42 g

Mass of chlorine = 44.5 g

Molecular weight of carbon = 12 g

Molecular weight of hydrogen = 1 g

Molecular weight of chlorine = 35.4 g

First, calculate the moles of each element,

                      Moles = given mass/ molecular weight

Moles of carbon = 5.03/12 = 0.42

Moles of hydrogen = 0.42/1 = 0.42

Moles of chlorine = 44.5/ 35.4 = 1.26

Divide the moles of each element by the smallest number of moles,

0.42 mol of C/ 0.42 = 1 C

0.42 mol of H/ 0.42 = 1 H

1.26 mol of Cl/0.42 = 3 Cl

The ratio of elements is 1:1:3

Therefore the empirical formula of the compound will be CHCl₃.
