If you reacted 183 grams of copper sulfate with excess iron, what mass of copper would you expect to make? You may need to balan
Nezavi [6.7K]

The question does not provide the equation

Answer:-

72.89 grams

Explanation:-

The balanced chemical equation for this reaction is

CuSO4 + Fe --> FeSO4 + Cu

Molecular weight of CuSO4 = 63.55 x 1 + 32 x 1 + 16 x 4

= 159.55 gram

Atomic weight of Cu = 63.55 gram.

According to the balanced chemical equation

1 CuSO4 gives 1 Cu

∴159.55 gram of CuSO4 would give 63.55 gram of Cu.

183 gram of CuSO4 would give 63.55 x 183 / 159.55

= 72.89 grams of Cu

a rectangular piece of aluminum foil measures 13.72 cm x 8.63 cm and has a mass of 3.1 g. Find how thick it is
Leona [35]

The two dimensions of aluminum foil are given 13.72 cm and 8.63 cm respectively with mass  3.1 g.

The density of aluminum is 2.7 g/cm^{3}. It is defined as mass per unit volume thus, volume of aluminum can be calculated as follows:

V=\frac{m}{d}

Putting the values.

V=\frac{3.1 g}{2.7 g/cm^{3}}=1.148 cm^{3}

The volume of cuboid is l\times b\times h, the length and breadth are given, height can be calculated as follows;

h=\frac{V}{l\times b}

Putting the values,

h=\frac{1.148 cm^{3}}{(13.72 cm)(8.63 cm)}=0.009695 cm

Or, approximately 9.7\times 10^{-3}cm

Therefore, thickness of aluminum foil is 9.7\times 10^{-3}cm
