Calculate the percent mass by volume for 19.0g of a lithium carbonate dissolved in 200.0 mL...
Calculate the mass percent if 25.0 grams of sodium carbonate is dissolved in 245 grams of water.
8. What is the percent by mass of lithium nitrate in a mixture of lithium nitrate and lithium carbonate if 0.500 g of the mixture reacts with (excess) 6 M aqueous solution of nitric acid to give 0.673 g of lithium nitrate? Water and carbon dioxide are the other products of the reaction. Assume that all lithium nitrate that could be made was and was isolated and weighed.
What mass of lithium carbonate, Li2CO3, is required to make 233 mL of a solution 1.6 M ?
The mass of zinc carbonate that is dissolved in 150 mL of a saturated solution is _________ grams.
1) Calculate the volume in mL for a solid block given that its mass is 19.0g and its density is 4.0g/mL. *Please explain steps* 2) Show the calculation and the answer to the correct number of significant digits. (123.000g – 112.990g)(0.6305) -------------------------------------------- (1.6000mL)(7.07x10-1)
The mass of magnesium hydroxide that is dissolved in 125 mL of a saturated solution is grams. The mass of lead carbonate that is dissolved in 150 mL of a saturated solution is grams. The volume of water needed to dissolve 0.0606 grams of calcium chromate is L. Assume no volume change upon addition of the solid.
12.25 g of lithium carbonate are dissolved to create a 1.25 L solution. What is the solution's molarity?
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...
