Carry out the following calculation, paying special attention to significant figures, rounding, and units (mol = mole, the SI unit for amount of substance): $frac{(6.022 imes 10^{23} ext{ molecules/mol})(1.23 imes 10^{1} ext{ g})}{60.13 ext{ g/mol}} = oxed{ ext{ }} imes 10^{oxed{ ext{ }}} ext{ molecules}$

Step 1
23 x 10' g) to moles using the molar mass (60.13 g/mol). Moles = (1.23 x 10' g) / (60.13 g/mol) Now, we need to multiply the moles by Avogadro's number (6.022 x 10^23 molecules/mol) to find the number of molecules. Show more…

Be sure to answer all parts. Enter your answer in scientific notation. Carry out the following calculation, paying special attention to significant figures, rounding, and units (mol = mole, the Sl unit for amount of substance): (6.022 × 1023 molecules/mol)(1.23 × 102 g) 63.53 g/mol
Carry out each calculation, paying special attention to significant figures, rounding, and units (J 5 joule, the SI unit of energy; mol 5 mole, the SI unit for amount of substance): (a) $\frac{\left(6.626 \times 10^{-34} \mathrm{J} \cdot \mathrm{s}\right)\left(2.9979 \times 10^{8} \mathrm{m} / \mathrm{s}\right)}{489 \times 10^{-9} \mathrm{m}}$ (b) $\frac{\left(6.022 \times 10^{23} \text { molecules/mol) }\left(1.23 \times 10^{2} \mathrm{g}\right)\right.}{46.07 \mathrm{g} / \mathrm{mol}}$ (c) $\left(6.022 \times 10^{23} \text { atoms/mol) }\left(2.18 \times 10^{-18} \mathrm{J} / \text { atom }\right)\left(\frac{1}{2^{2}}-\frac{1}{3^{2}}\right)\right.$, where the numbers 2 and 3 in the last term are exact
