Answer:
Explanation:
In this case, according to the Periodic table
there is 1g of hydrogen per mole. As we know that dihydrogen (H2) has two hydrogen atoms per molecule. So,there will be 2*1g hydrogen per mole=2g dihydrogen per mole.
If there is 2g dihydrogen per mole,and we have 4g,then we know that there is 2 mole dihydrogen in 4g.And for hydrogen there is 4 moles in 4g of hydrogen
Answer:
The molar mass is 138.8843 g/mol
Answer:
The substance formed is KCl aqueous
Explanation:
When a salt is added water to it it changes from a solid to be aqueous
