Question

How many grams of nacl can be prepared from 4.2 moles of cl2

Answer 1

Answer:

4.1 g ..

Explanation:

I hope its correct..

see first we know

1 mole of cl2 produce Nacl=1 mole

so 4.2 mole of cl2 will produce Nacl =4.2×1=4.1 mole .... no we need answer in grams so we use basic unitary method to convert moles to grams

...

58.5 g = molecular mass of Nacl

We knoww

58.5g has 6.022×10^23moles

so from here see picture for reference
