Answer:
1.0555 * 10^24 molecules
Explanation:
Number of molecules = ?
Mass = 3.79 Kg = 3790 g
Molar mass of Cs7(Cr5O3)4 = 2162.25 g/mol
Number of moles = Mass / Molar mass
Number of moles = 3790 g / 2162.25 g/mol
Number of moles = 1.7528 mol
1 mol = 6.022 * 10^23 molecules
1.7528 mol = x
solving for x;
x = 6.022 * 10^23 * 1.7528
x = 1.0555 * 10^24 molecules
Answer:
Melamine is used for making tableware,cooking utensils, plates, plastic products etc.
Explanation:
Melamine is used to manufacture many products. How? Well melamine-formaldehyde resin, as it's full name, forms molecular structures that are molded, with heat, to take the shape of the items such as tableware.
After this chemical reaction takes place, the "left over" remains as plastic.
