Question

Covert 175g of H2O into moles.

Answer 1

9.72 moles.

Step-by-step explanation:

From the question given above, the following data were obtained:

Mass of H₂O = 175 g

Number of mole H₂O =?

Next, we shall determine the molar mass of H₂O. This can be obtained as follow:

Molar mass of H₂O = (2×1) + 16

= 2 + 16

= 18 g/mol

Finally, we shall determine the number of mole H₂O. This can be obtained as follow:

Mass of H₂O = 175 g

Molar mass of H₂O = 18 g/mol

Number of mole of H₂O =?

Mole = mass /Molar mass

Number of mole of H₂O = 175/18

Number of mole of H₂O = 9.72 moles
