hello i need help for these questions thank you

Perform the calculations and determine the absolute and percent relative uncertainty. Express each answer with the correct number of significant figures. To avoid rounding errors, do not round your answers until the very end of your calculations. 19.8 (+0.3) - 2.31 (+0.01)] 0.88 8.5 (+0.6) Correct Answer 0.07 absolute uncertainty: Correct Answer 8 percent relative uncertainty: F % Correct Answer 0.10 9.2 (+0.4) x ([5.4 (+0.3) x 10-3] + [5.6 (+0.1) x 10-"]) = Incorrect Answer 0.005 absolute uncertainty: Correct Answer 5 percent relative uncertainty: Correct AnswerPerform the calculations and determine the absolute and percent relative uncertainty. Express each answer with the correct number of significant figures. To avoid rounding errors, do not round your answers until the very end of your calculations. 2.0398 [8.47 (+0.06)]1/3 Incorrect Answer 0.005 absolute uncertainty: Correct Answer 0.2 percent relative uncertainty: F % Correct Answer 0.817 log [6.56 (+0.05)] = Correct Answer 0.00038 absolute uncertainty: Incorrect Answer 0.046 percent relative uncertainty Incorrect AnswerA solution of HNO, is standardized by reaction with pure sodium carbonate. 2H+ + Na,CO, - 2 Na+ + H,O + CO, A volume of 25.14 + 0.05 mL of HNO, solution was required for complete reaction with 0.8544 + 0.0009 g of Na, CO., (FM 105.988 + 0.001 g/mol). Find the molarity of the HNO, solution and its absolute uncertainty. Note: Significant figures are graded for this problem. To avoid rounding errors, do not round your answers until the very end of your calculations. 0.6412 0.00000261 [HNO, ] = M M Incorrect Answer Incorrect
