<h3><u>Answer;</u></h3>
Molarity = 0.25 M
<h3><u>Explanation;</u></h3>
Molarity is given by moles/Liter.
First we find moles:
Number of moles = Mass /molar mass
= (10.7g NH4Cl)/(53.5g/mol NH4Cl)
= 0.200 moles NH4Cl
Then we convert to liters:
= (800mL)*(1L/1000mL) = 0.800L
Therefore; molarity = 0.2moles/0.8L
= 0.25M
( 6.50 mol * 17 mol * 1.0079g )/ 8 mol = 13.9 grams

Answer:
The process when two or more atoms are joined together to make
Explanation:
Nuclear fission is the process where two or more atomic nuclei joined together to make a new or more atomic nuclear or particles. Energy is released. This process releases energy because the total mass of the r single nucleus or nuclei formed is lesser than the mass of the two original nuclei or the reactants.
