My homework is 10 questions. I would perfer to have this done as soon as possible and I will pay extra if it can be done in a short amount of time. This is online homework so I can let you know immediately if it is incorrect. Thanks alot. 1. If a sample of LiNO3 is found to contain 2.03 ú 1018 N atoms how many moles of O atoms are present? Express your answer in scientific notation. 2. If a sample of CO is found to contain 2.78 ú 1018 O atoms how many CO molecules are present? Express your answer in scientific notation. 3. How many C atoms are present in 0.902 g of C2H4 molecules? Express your answer in scientific notation. 4. How many moles of Co atoms are present in 5.91 ú 1019 Co[P(CH3)3]4 molecules? Express your answer in scientific notation. 5. How many moles of O atoms are present in 6.55 ú 1022 F2SO2 molecules? 6.
