Calculate the number of moles in 5.63 grams of potassium (K). Additional Information: • If needed, use the periodic chart values from the printable Periodic chart provided with this course. • If needed use 6.022 x 1023 for Avogadro's number. Format your answer: . With three significant figures Include the correct unit. Your Answer:
How many moles of zirconium are in 8.5 x 1022 atoms of zirconium (Zr)? Additional Information: • If needed, use the periodic chart values from the printable Periodic chart provided with this course. . If needed use 6.022 x 1023 for Avogadro's number.
The molecular mass of a compound with an empirical formula of NO₂ is 184.04 g/mol. What is the molecular formula? Format your answer like this: . Write the N before the O. • Do NOT use a ZERO to represent the O or the system will count your answer as wrong.) • You will not be able to type subscripts. Just type the numbers where they go. For example, S203 would be typed in as S203.
49.410% potassium, sulfur, and 30.32% oxygen are found to be in a sample found in an unlabeled container. What is the empirical formula of this compound? • Write the K then the S then the O. • Do NOT use a ZERO to represent the O or the system will count your answer as wrong.) • You will not be able to type subscripts. Just type the numbers where they go. For example, S₂O3 would be typed in as S203. • Remember, you never include 1 in the formula.
This is an impossible formula. If it were real, determine the percent abundance of H. C3H₂O2
