2.12 g pill
CaCO3 = mass of Ca / total mass = 40 / (100) = 0.4
then
1.37 g = 1.37*0.4 = 0.548 g of Calcium
then
%mass of Ca = Ca/totla Mass * 100 = 0.548/(2.12) *100% = 25.84905 % of Ca in sample
What is the percent mass of calcium supplement if 1.37 g of calcium carbonate from a2.12g...
1)Once acid was added to the supplement, what was the purpose of filtering the solution? A) To remove the solid impurities B) To remove the calcium ion from the solution C) To remove the aqueous impurities D) To obtain solid calcium 2) When sodium carbonate is added to the filtrate, fizzing occurs. Which gas is being produced? A) carbon dioxide B) carbon monoxide C) water D) oxygen 3) What was the purpose of heating the calcium carbonate precipitate? A) to...
The active component in one type of calcium dietary supplement is calcium carbonate. A 1.2450-g tablet of the supplement is added to 50.00 mL of 0.5000 M HCl (aq) and allowed to react. After completion of the reaction, the excess HCl (aq) requires 40.65 mL of 0.2535 M NaOH (aq) for its titration to the equivalence point. What is the calcium content of the tablet, expressed in milligrams of Ca^2+? m_ca^2+ = mg
A tablet containing calcium carbonate and fillers with a mass of 1.631 g was dissolved in HCl. After the fillers were filtered out, the HCl was neutralized by adding sodium carbonate. The resulting precipitate was pure calcium carbonate (with the fillers removed). The solid calcium carbonate was collected on a watch glass that had a mass of 46.719 g when empty. After the calcium carbonate had been allowed to dry, the mass of the watch glass plus product was found...

A 0.510-g sample of calcium chloride reacts with sodium carbonate to give 0.366 g of calcium carbonate precipitate. What is the percent yield? 3
Calcium carbonate, CaCO_3, decomposes upon heating to calcium oxide and carbon dioxide. What mass of solid calcium carbonate is required to produce 2.40 liters of carbon dioxide measured at STP? (A) 10.7 g (B) 21.4 g (C) 50.0 g (D) 100. g
A 18.5 g sample of a mixture of magnesium carbonate and calcium carbonate is treated with excess HCl. The resulting reaction produces 5.23 L of carbon dioxide gas at 28 °C and 753 torr. Write a balanced chemical equation for the reaction that takes place between magnesium carbonate and HCl. Include physical states. chemical reaction: Write a balanced chemical equation for the reaction that takes place between calcium carbonate and HCl. Include physical states. chemical reaction: Calculate the total number...
What is the limiting reactant of potassium carbonate and calcium chloride? 2.5 g of potassium carbonate and 2.0 g of calcium chloride were used. K2CO3(aq) + CaCl2(aq) -> CaCO3(s) + 2KCl(aq)
a and bQuestion: What is the percentage yield of calcium carbonate formed when calcium chloride reacts with sodium carbonate? PART A: Use the balanced chemical equation below to determine: (a) the limiting reactant (b) theoretical yield (mass) of calcium carbonate \(\underset{\mathrm{m}=3.75 \mathrm{~g}}{\mathrm{Na}_{2} \mathrm{CO}_{3}(\mathrm{qq})}+\underset{\mathrm{m}=4.82 \mathrm{~g}}{\mathrm{CaCl}_{2}(\mathrm{oq})} \rightarrow \underset{\mathrm{m}=?}{\mathrm{CaCO}_{3}(\mathrm{~s})}+2 \mathrm{NaCl}_{(\mathrm{oq})}\)
