Substance A and B are colorless, odorless liquids that are nonconductors and flammable. The density of substance A is 0.97 g/mL;

tekilochka [14]

Answer:

A and B are not the same substances.

The reason is because they do not have the same density which is a function of their masses and volumes.

For instance, for every Volume of 1mL of each substances, A has a mass of 0.97g which is different from the 0.89g of B.

Help!!!

kupik [55]

Answer:

1. 0.82 gram of Ag+

2. 4.79 g of Ag₂O₃S

Explanation:

From the given information:

Total amount of Ag₂O₃S = 2.24 grams

Atomic mass of Ag+ =107.86 g/mole

molar mass of Ag₂O₃S = 295.8 g/mole

∴

The mass of the Silver (Ag) in grams is:

$= Total\ amount \ of \ Ag^+ \times \dfrac{107.86 \ g/mol}{295.8 \ g/mol}$

$=2.24 \times \dfrac{107.86 \ g/mol}{295.8 \ g/mol}$

= 0.82 gram of Ag+

Here, the total amount of Ag₂O₃S = unknown

Atomic mass of Ag+ = 107.86 g/mole

molar mass of Ag₂O₃S = 295.8 g/mole

amount of Ag+ = 1.75 g

∴

The mass of Ag₂O₃S = $Total \ amount \ of \ Ag^+ \times \dfrac{295.8 \ g/mol}{107.86\ g/mol}$

$=1.75 \times \dfrac{295.8 \ g/mol}{107.86\ g/mol}$

= 4.79 g of Ag₂O₃S
