What is the concentration in mm percent of a solution prepared from 50.0g Na-Cl and 150.0g of water?
To find the concentration in mass percent, first calculate the total mass of the solution (50.0g NaCl + 150.0g water = 200.0g total). Then, divide the mass of NaCl by the total mass of the solution and multiply by 100 to get the concentration in mass percent: (50.0g NaCl / 200.0g total) * 100 = 25.0% NaCl.
What types of stone are part of the dimension stone industry?

When a 1.25-gram sample of limestone was dissolved in acid 0.44 gram of CO2 was generated if the rock contained no carbonate other than CaCO3 what was the percent of CaCO3 by mass in the limestone?
CaCO3 +2HCl ------------> CaCl2 + CO2 + H2O number of moles of CO2 in .44 grams = .44/ 44 = .01 From equation it is clear that 1 mole of CO2 is produced from CaCO3 = 1 mole .01 mole of CO2 is formed from CaCO3 = .01 mole Weight of .01 mole of CaCO3 is = .01mole *100 g/mole = 1 gram weight % of CaCO3 is = 1*100/ 1.25 = 80 % w/w I've post my answer, so why don't you show that answer here with the question. It's fare. I must be informed about my answer weather it is right or wrong. Please inform me at amitmahalwar@yahoo.com
How would the following observations affect the calculated percent composition of each component if there is a small amount of white powder left in the sample container after heating the contents to t?
If there is a small amount of white powder left in the sample container after heating, it suggests incomplete decomposition of the sample. This would lead to an underestimation of the percent composition of the volatile components, as not all of it would have been driven off during heating. The remaining white powder could be a non-volatile component, affecting the overall calculation of percent composition.
How do you calculate percent Calcium Nitrate using the percent calcium and the percent nitrate results?
To calculate the percent Calcium Nitrate, you can add the percentage of Calcium and Nitrate together. For example, if you have 15% Calcium and 10% Nitrate, the percent Calcium Nitrate would be 25%. This assumes that the percentages are based on the weight of the compound.
