Zn + CuSO4 --> ZnSO4 + Cu
1.75g CuSO4 * (1moleCuSO4/159.62gCuSO4) * (1moleZn/1moleCuSO4) * (65.38gZn/1moleZn) = .7168g Zn
2.00g Zn - .7168g Zn = 1.2832g Zn in Excess
The yield is 100 %.
175g = 6.17oz
180 grams of FLOUR is 1.5 cups
The mass in grams of 3,20 moles of copper is 158,865 g.
well there are 25g in an oz so 25 x 7= 175g :)
18 level tablespoons is 175g flour which is 6oz.
Grams is a measure of weight, whereas tbl is a measure of volume. Hence there is not a standard conversion. This can only be converted if you state what substance you wish to convert - for example, 175g of lead cooking weights will be a smaller volume and hence fewer tablespoons than say, 175g of feathers will require.
2Al (s) + 3CuSO4(aq) ==> Al2(SO4)3 + 3Cu ... balanced equation1 mol CuSO4 x 2 mol Al/3 mole CuSO4 = 0.67 moles Al required.

100, of course.
