What is molar mass of a gas if 0.0494g of the gas occupies a vol of 0.153 l at temperature of 26c and a pressure of 0.998 atm?

Explanation:

We can use the Ideal Gas Law to solve this problem

pV = nRT

Data:

p = 0.998 atm

V = 0.153 L

T = 26 °C

m = 0.0494 g

1.  Convert temperature to kelvins

T = (26 + 273.15) K =  299.15 K

2. Calculate the number of moles

3. Calculate the molar mass

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

⇌(double head arrow) means reversible reaction).
