If an acid is made from the anion SO42-, what would it's formula be?
KatRina [158]

<u>Answer:</u> The chemical formula of the compound formed is H_2SO_4

<u>Explanation:</u>

Acids are defined as the chemical species which donate hydrogen ions when dissolved in water.

HA(aq.)\rightarrow H^+(aq.)+A^-(aq.)

Ionic compound is formed by the complete transfer of electrons from 1 atom to another atom. The cation is formed by the loss of electrons by metals and anions are formed by gain of electrons by non metals.

We are given:

An anion having chemical formula SO_4^{2-} named as sulfate ion

This will combine with 2 hydrogen ions to form a neutral compound. The neutral compound formed is sulfuric acid.

Hence, the chemical formula of the compound formed is H_2SO_4

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.
