(A tablet containing calcium carbonate and fillers with a mass of 1.631 g was dissolved in HCl. After the fillers were filtered
FrozenT [24]

Answer:

1) 0.825 grams is the mass of pure calcium carbonate product collected at the end of the experiment.

2) The mass % calcium carbonate in the tablet is 50.58%.

3) The mass % of calcium in calcium carbonate  is 40.00 %.

4) Mass of calcium in a tablet is 0.33 g.

Explanation:

Mass of tablet = 1.631 g

Mass of the watch glass = 46.719 g

Mass of the watch glass + mass of calcium carbonate = 47.544 g.

Mass of calcium carbonate = 47.544 g - 46.719 g = 0.825 g

0.825 grams is the mass of pure calcium carbonate product collected at the end of the experiment.

Mass of calcium carbonate = 0.825 g

Percentage of calcium in tablet:

\%=\frac{\text{Mass of calcium carbonate }}{\text{Mass of tablet}}\times 100

\%=\frac{0.825 g}{1.631 g}\times 100=50.58\%

The mass % calcium carbonate in the tablet is 50.58%.

Percentage of calcium in calcium carbonate :

Molar mass of calcium carbonate = 100 g/mol

Atomic mass of calcium = 40 g/mol

Percentage of calcium in calcium carbonate :

\%=\frac{\text{atomic mass of calcium}}{\text{Molar mass of}CaCO_3}\times 100

\%=\frac{40 g/mol}{100 g/mol}\times 100=40.00\%

The mass % of calcium in calcium carbonate  is 40.00 %.

Mass of calcium carbonate = 0.825 g

The mass % of calcium in calcium carbonate  is 40.00 %.

Mass of calcium in a tablet : x

40.00\%=\frac{\text{Mass of calcium in a tablet}}{0.825 g}\times 100

x=40.00\times \frac{0.825 g}{100}=0.33 g

Mass of calcium in a tablet is 0.33 g.
