Convert 14.55 g of H_(2)O to moles. 0.808 moles 0.598 moles 0.687 moles 0.866 moles Convert 1.75 moles of NaCl to grams. 89.7 grams 102.3 grams 105.2 grams 98.5 grams

To convert grams of $\mathrm{H}_{2} \mathrm{O}$ to moles, we use the molar mass of water. The molar mass of $\mathrm{H}_{2} \mathrm{O}$ is approximately 18.015 g/mol.

$$\text{Moles of } \mathrm{H}_{2} \mathrm{O} = \frac{14.55 \, \text{g}}{18.015 \, \text{g/mol}} \approx 0.808 \, \text{moles}$$

So, the correct answer is:
0.808 moles

To convert moles of NaCl to grams, we use the molar mass of NaCl. The molar mass of NaCl is approximately 58.44 g/mol.

$$\text{Mass of NaCl} = 1.75 \, \text{moles} \times 58.44 \, \text{g/mol} \approx 102.3 \, \text{grams}$$

So, the correct answer is:
102.3 grams
