Since there are lot of questions
According to HOMEWORKLIB POLICY only 1 question with 4 sub parts per post is allowed. please post the rest question seperately. So I can only solve the table for you
1. Average moles of Magnesium = (0.014+0.0168+0.0169) / 3 = 0.0159 mol
2. Stndard Deviation in mol of Mg
3. Average moles of Oxygen : (0.017+0.007+0.000644)/3 = 0.008214
4. Stndard Deviation in mol of oxygen :
