Question

40g of hydrogen atoms has how many mole​

Answer 1

Answer:

This QUESTION is INCOMPLETE

Explanation:

The equation is needed to solve this question.

ways to solve for moles (n);

1. n= m/mr, (m= mass mr= molecular mass)

2. n= c × v  ( c= concerntration v= volume)

3. n= v/vm  ( v= volume vm= molar volume)

4. Molar Ratio.

1. how to solve for mr

e.g. H20

*Find the atomic mass for each element.

h=1

o=16

* over here there is 2 atoms of H

so you have to multiply 1 with 2

= 2

2+16=18(mr)

2. The VM which is molar volume is a constant which means anywhere VM is used it is used as the value "24".

3. For the molar ratio (which your question is uses) u need the chemical equation
