Calculate the atomic mass in grams of 0.35 moles of ch4

5.6 grams

Explanation:

To calculate the moles, we use the equation:

Thus mass =

For

Moles of = 0.35 moles

Molar mass of = 16 g/mol

Putting values in above equation, we get:

mass =

The atomic mass of 0.35 moles of is 5.6 grams.

14,16 18 reacts with group

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.
