The mass of Au is 19.7 g

The chemical reaction may be

Au₂S₃ + 3H₂ → 2Au + 3H₂S

1 mole of Au₂S₃ gives 2 mole of Au

Then 0.0500 mol of Au₂S₃ gives

0.0500 × 2 / 1

= 0.10 moles.

To find mass

Mass = moles × molar mass

Moles = 0.10.

Molar mass = 197 g

Mass = 0.10 × 197

         = 19.7 g

Hence the mass of Au produces is 19.7 g

How many liters of a 4.0 M CaCl2 solution would contain 2 moles of CaCl2?
nekit [7.7K]

Answer:

The answer to your question is 0.5 liters

Explanation:

Data

[CaCl₂] = 4.0 M

number of moles = 2

volume = ?

Process

To solve this problem use the formula of Molarity and solve it for volume, substitute the values and simplify.

-Formula

Molarity = moles / volume

-Solve for volume

Volume = moles / molarity

-Substitution

Volume = 2/4

-Simplification

Volume = 0.5 liters.

How do you tell by the formula that an element on the periodic table is a metal
Dmitrij [34]
The metalloids are on the right side of the periodic table B, Si, Ge, As, Sb, Te, and At. The nonmetals are also on the right side next to the metalloids, there should be a He at the top right of the periodic table and there should be one more nonmetal at the top left of the periodic table that is H. And from the metals they are all on the middle next to the metalloids, starting from Li, Be, Na, and Mg as so on all of those are metals.

A brick has it dimensions of 25 cm x 5 cm x 15 cm so what is the volume of the brick in cubic meters
Sveta_85 [38]
Well the formula for the volume of a cube is

V=length×width×height

so input it

V=25×5×15

V=1875 cubic meters
