ensure the equation is balanced.
obtain the mole ratio between Zn and Ag i.e. 1 mole of Zn produces 2 moles of Ag
convert the mass of Ag (m=5.4g) into mole using m/Mr where Mr is the molar mass of Ag.
take note of that mole for Ag and use it to calculate the mole for Zn, using the mole ratio.
then convert the mole for Zn to mass using the same formula m/Mr to get your required mass of Zn.
Zn(s) + 2AgNO3(aq) = 2Ag(s) + Zn(NO3)2 (aq)
It would require_____g of zinc to produce 5.40g of silver.
