A 0.4230 g sample of impure sodium nitrate was heated, converting all the sodium nitrate to .1235 g of sodium nitrate and oxygen gas. Determine the percent of sodium nitrate in the original sample.
Answer:2HNO3 = 2HNO2 + O2m= 85 x 0.1235 / 69= 0.1521W%= 0.1521 / 0.4230 = 36%

<ol><li>A student has a piece of silver. The density of silver is 14.09g/cm3. If the mass of the piece of silver is 89.05g, what is the volume, in cm3, of the piece of silver? </li></ol>
Accordng to the equation, the volume can be determined as following:V = m/dwhere m - mass, d - density, V - volume.From here:V = 89.05 g / 14.09g/cm3 = 6.32...
