Assuming an efficiency of 30.80%, calculate the actual yield of magnesium nitrate formed from 147.4 g of magnesium and excess copper(II) nitrate. write the number in grams.
Mg+Cu(NO3)2=Mg(NO3)2+Cu
is anyone able to solve this? ive gotten the answer wrong twice
Mg+Cu(NO3)2=Mg(NO3)2+Cu
is anyone able to solve this? ive gotten the answer wrong twice

moles Mg = 147.4 g / molar mass Mg
moles Mg(NO3)2 = moles Mg * .3080
mass Mg(NO3)2 = moles Mg(NO3)2 * molar mass Mg(NO3)2
moles Mg(NO3)2 = moles Mg * .3080
mass Mg(NO3)2 = moles Mg(NO3)2 * molar mass Mg(NO3)2
