How many moles of aspartame are present in 1.00 mg of aspartame?
Diano4ka-milaya [45]

Answer:- There are 3.40*10^-^6 moles.

Solution:- It is a unit conversion problem where we are asked to convert mg of aspartame to moles. Aspartame is C_1_4H_1_8N_2O_5 and it's molar mass is 294.31 grams per mole.

mg are converted to grams and then the grams are converted to moles as:

1.00mg Aspartame(\frac{1g}{1000mg})(\frac{1mole}{294.31g})

= 3.40*10^-^6 moles of aspartame

So, there would be 3.40*10^-^6 moles of aspartame in 1.00 mg of it.

Which two properties are used to define matter?
Fantom [35]
The two properties which are used to define matter are that it has mass and it takes up space. The other properties do not necessarily apply to each matter. Such some matter can be a conductor of heat (such as metal) and some not (such as non metals). Likewise, some matter can be buoyant and float on liquid of density more than it but others would not on the liquids of density less than it. In-fact not all the matters are conductors of energy (such as heat, sound, electricity) or at-least a very poor conductor of energy and tend to find application as insulating agents (non conductors). So the only thing which is necessarily true is that the matter would definitely have mass in even their minutest form as atom and would take up some space.

Chloral, Cl3C―CH═O, reacts with water to form the sedative and hypnotic agent chloral hydrate, Cl3C―CH(OH)2. Draw Lewis structur
Paul [167]

Answer:

See attached figure.

Explanation:

Hello there!

In this case, according to the given substances, we recall the concept of Lewis structure as such showing the bonds and valence electrons each atom has in the molecule. Thus, since chlorine atoms have seven valence electrons, carbon atoms four of them, hydrogen atoms have 1 and oxygen atoms 6, we are able to draw such Lewis dot structures, by obeying the octet as shown on the attached figure.

Best regards!
