Question 34 How many grams of oxygen (O) are present in a 6.35 g sample of potassium nitrate (KNO3)? Enter your answer in decimal form with the correct number of sig figs. Use the proper abbreviation for the units. NOTE: If you have taken chemistry before and know what diatomic means, do not take that into consideration. Use just O for this. There are reasons for this. Your Answer: Answer units

Please help! Question: Label each part of the apparatus

Answer B, show all work and correct number of sig figs.

How many grams of H2SO4 are present in 1.9*1026 formula units of H2SO4 ? Round your answer to 1 decimal place. Your Answer: Answer units

Results table. To clean up, zoom out from the balance and drag the sample to the red disposal container. Repeat with ammonium chloride (NH4Cl), located on the Salts shelf.                                     C12H22O11                                              NH4ClMass (g)                        1.0481 g                                                  1.0444g  Molar Mass (g/mol)MolesMoles of each elementAtoms of each element Much like the previous calculation, you will use the periodic table to determine the molar massof the compound. The example shown is for sodium chloride, NaCl. The molar mass is the massof 1 sodium (22.98g/mole) and 1 chlorine (35.45g/mole) added together, 58.43g/mole. If theformula shows multiple atoms, as in sugar, you must take that into account. For sugar, it will be12 times the mass of a carbon atom plus 22 time the mass of hydrogen atom, plus 11 times themass of oxygen atoms.The calculation of moles will be similar to that done in the previous…
