Question
Add the following measurements and round off the answer:$ \begin{array}{llc} \text { (a) } & 0.4 \mathrm{~g} & \text { (b) } & 15.5 \mathrm{~g} \\ & 0.44 \mathrm{~g} & & 7.50 \mathrm{~g} \\ + & 0.444 \mathrm{~g} & & +0.050 \mathrm{~g} \\ \hline \end{array} $
Step 1
For option (a), we have: \[0.4 \, \text{g} + 0.44 \, \text{g} + 0.444 \, \text{g} = 1.284 \, \text{g}\] For option (b), we have: \[15.5 \, \text{g} + 7.50 \, \text{g} + 0.050 \, \text{g} = 23.050 \, \text{g}\] Show more…

Subtract the following measurements and round off the answer: (a) $ \begin{array}{rrr} 242.197 \mathrm{~g} & \text { (b) } & 27.55 \mathrm{~g} \\ -175 & \mathrm{~g} & & -14.545 \mathrm{~g} \\ \hline \end{array} $
Add 0.0025 kg, 1750 mg, 2.25 g, and 825,000 μg, and express the answer in grams.
Divide the following measurements and round off the answer: (a) $66.3 \mathrm{~g} / 7.5 \mathrm{~mL}$ (b) $12.5 \mathrm{~g} / 4.1 \mathrm{~mL}$ (c) $42.620 \mathrm{~g} / 10.0 \mathrm{~mL}$ (d) $91.235 \mathrm{~g} / 10.00 \mathrm{~mL}$
