Add the decimal numbers. Then round the numbers and find the sum to determine if your answer is reasonable. The first estimate is done for you. $$ 3.451+7.339 $$

Estimate an approximate answer for each of the following calculations. Verify your ballpark answer using a calculator: $$\begin{array}{l}\text { (a) } 0.750 \mathrm{~g} \mathrm{Mg} \times \frac{1 \mathrm{~mol} \mathrm{Mg}}{24.31 \mathrm{~g} \mathrm{Mg}}\times\frac{1\mathrm{~mol} \mathrm{MgO}}{1 \mathrm{~mol} \mathrm{Mg}} \times \frac{40.31 \mathrm{~g} \mathrm{MgO}}{1 \mathrm{~mol} \mathrm{MgO}} \\=? \mathrm{~g} \mathrm{MgO}\end{array}$$
