From this data, calculate (a). the percentage of CaCl2 in the original sample and (b). the formula of the hydrate Mass of crucible + cover = 28.39 g Mass of crucible + cover + sample = 30.41 g Mass of crucible + cover + residue = 29.75 5. The chemical analysis of a binary hydrate shows that it is composed of 27.76% Mn, 35.82% Cl and 36.41% H20. a. What is the formula of the hydrate? b. What is the name of the hydrate?
B. TRUE OR FALSE: Read each statement carefully. Write TRUE if the statement is correct and FALSE if the statement is incorrect. 6. It is important to know the chemical formula of compound in order to calculate its percentage composition _7. Percentage composition describes the actual number of atoms of each element in a given compound _8. The percent by mass of a compound can be computed using this formula, (mass of an element per mole/molar mass of compound) x 100 _9. You can use percent composition to get the number of grams in a given compound. 10. Percent composition determine the amount (in percent) of each element present in a compound. C. Solve the given problem. Write your calculations on the provided answer sheet. Paracetamol (C3H,NO2) an organic compound made up of C, H, O and N. It is a common medicine to treat fever and pain because it is an anti-inflammatory drug. Determine the elemental percentage composition of a paracetamol.
A student finds that they have 0.2545 g of NH4Cl, 1.1502 g of NaCl, and 1.0181 g of SiO2. Calculate the percent gained or lost during this experiment if the initial mass of the mixture was 2.5537 g.
(a) A mixture sample containing 80% NaHCO3 and 20%NaCl was marketed for certain food preparations. As an analytical chemist, you took a 2.00 g of the mixture and heated it until the decomposition reaction was complete and found the final mass was 1.02 g. Based on this, calculate the percent of NaHCO3 in the mixture. Assuming 80% is the actual value, what is the percent error in your measurement?
