N analyst prepared a sucrose solution by weighing 1kg of water and add 1.5kg sucrose.estimate the concentration of the resultant

makvit [3.9K]

The concentration of the solution in mass percent is 60%.

<h3>What is the mass percent?</h3>

The concentration of a substance can be expressed in mass percent. This refers to the percentage of the solute that is contained in the solution.

Thus we can write;

Mass percent = Mass of solute/ Mass of solution * 100/1

Mass percent = 1.5kg/1.5kg + 1 Kg * 100/1

Mass percent = 60%

Hence, the concentration of the solution in mass percent is 60%.

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. In

kodGreya [7K]

Answer: The net chemical equation for the production of acrylic acid is given below.

Explanation:

We are given two intermediate equations:

Equation 1: $CaC_2(s)+2H_2O(g)\rightarrow C_2H_2(g)+Ca(OH)_2(s)$

Equation 2: $6C_2H_2(g)+3CO_2(g)+4H_2O(g)\rightarrow 5CH_2CHCO_2H(g)$

To get the net chemical equation for the formation of acrylic acid from calcium carbide, carbon dioxide and water, we multiply the first equation by a factor of '6'.

The equation becomes:

Equation 1: $6C_2H_2(g)+6Ca(OH)_2(s)$
