Calculate the mass of 6.9 moles of nitrous acid (HNO2). Show work.

324.3g

Explanation:

number of moles=mass/molecular mass

the number of moles is already in the question which is 6.9moles.whats needed is the mass to find the mass we also have find the molecular mass

(HNO2)

molecular mass=47

mass=n×MR

=6.9×47

=324.3g

I hope it helps
