The given question is incomplete. The complete question is as follows.
The chemical formula for rubidium chloride is RbCl . A chemist determined by measurements that moles of rubidium chloride participate in a chemical reaction are 6.05 mol. Calculate the mass of rubidium chloride that participates. Be sure your answer has the correct number of significant digits.
Explanation:
It is known that number of moles is equal to mass divided by molar mass of the substance.
Mathematically, No. of moles = [tex]\frac{mass}{\text{molar mass}}[/tex]
It is known that molar mass of RbCl is 120.921 g/mol. Hence, calculate the mass of RbCl for 6.05 mol as follows.
No. of moles = [tex]\frac{mass}{\text{molar mass}}[/tex]
6.05 mol = [tex]\frac{mass}{120.921 g/mol}[/tex]
mass = 731.57 g
therefore, we can conclude that mass of rubidium chloride that participates is 731.57 g.
