a. How many ATOMS of hydrogen are present in \( 9.77 \) grams of water? atoms of hydrogen . b. How many GRAMS of oxygen are present in \( 6.46 \times 10^{22} \) molecules of water? grams of oxygen . 9 more group attempts remaining
For the molecular compound disulfur decafluoride, what would you multiply "grams of \( S_{2} F_{10} \) " by to get the units "molecules of \( S_{2} F_{10} \) "? \[ \mathrm{g} \mathrm{S}_{2} \mathrm{~F}_{10} \times \stackrel{\square}{=} \times \text { molecules } \mathrm{S}_{2} \mathrm{~F}_{10} \] Drag and drop your selection from the following list to complete the answer: 9 more group attompts remaining
Expert Answer
Q- 0a ; The parameters are given ; mass of water = 9.77 g ; molar mass of water = 18 g/mol Moles of water = mass of water / molar mass of water = 9.77 g / 18 g/mol = 0.543 mol We know that one mole of any substance is equal to Avogadro’s number, 6.02
