A sealed glass tube contains 2.25 g of copper and 3.32 g of sulfur. The mass of the tube and its contents is 18.48 g. Upon heating, a reaction forms copper(II) sulfide (CuS). All of the copper reacts, but only 1.14 g of sulfur reacts. Predict what the mass of the tube and its contents will be after the reaction is completed. Explain your reasoning

How to calculate percentage composition by …

formula mass of carbonate, CO 3 = 12 + 48 = 60 (same for the carbonate ion) formula mass sodium hydrogencarbonate = 23 + 1 + 60 = 84. therefore the scale up factor is 84/60 = 1.4. so, minimum percentage sodium hydrogen carbonate in the mixture should be 50 x 1.4 = 70% NaHCO 3 . Example 4b.7. In an experiment 6.0 g of metal M was burned in

formula mass of carbonate, CO 3 = 12 + 48 = 60 (same for the carbonate ion) formula mass sodium hydrogencarbonate = 23 + 1 + 60 = 84. therefore the scale up factor is 84/60 = 1.4. so, minimum percentage sodium hydrogen carbonate in the mixture should be 50 x 1.4 = 70% NaHCO 3 . Example 4b.7. In an experiment 6.0 g of metal M was burned in

What mass of sodium metal contains the …

12,00 g of carbon (provided it is carbon-12) contains, by definition, one mole of atoms. We must therefore establish the mass of one mole of sodium. The periodic table tells us that sodium has a molar mass of 22.99 g/mol, and so 22.99 grams of sodium contains the same nuer of atoms as 12.00 g of carbon. 391 views.

Chemistry Behind Airbags

Sodium azide (NaN 3) can decompose at 300 o C to produce sodium metal (Na) and nitrogen gas (N 2). The signal from the deceleration sensor ignites the gas-generator mixture by an electrical impulse, creating the high-temperature condition necessary for NaN 3 to decompose. The nitrogen gas that is generated then fills the airbag.

Thus, since the atomic mass of iron is 55.847 amu, one mole of iron atoms would weigh 55.847 grams. The same concept can be extended to ionic compounds and molecules. One formula unit of sodium chloride (NaCl) would weigh 58.44 amu (22.98977 amu for Na + 35.453 amu for Cl), so a mole of sodium chloride would weigh 58.44 grams.
