His measurements will be more precise if he takes measurements from an additional 100 flowers. B.) His measurements will be more accurate if he uses a graduated cylinder that measures to the nearest tenth of a mL. C.) His measurements will be more precise if he uses a graduated cylinder that measures to the nearest tenth of a mL. D.) His measurements will be more accurate if he takes measurements from an additional 100 flowers. NEED HELP NOW PLEASE!!!
1 mole of carbon contains 12 g Thus, 34.6 moles will contain; 34.6 × 12 = 415.2 g If a substance contains 89.2 % carbon, then, (415.2/89.2) ×100 = 465.47 g of the substance will be required to yield 34.6 moles of carbon.
