Answer 2

Answer:

350.2 grams.

To Find:

10.3 moles of H2O​.

Step-by-step explanation:

First find molecular weight of H₂O

weight of 1 mole of H₂ = 2 gm

weight of 1 mole of O = 32 gm

⇒ weight of 1 mole of H₂O = 34 gm

Now, find weight of 10.3 mole of H₂O

⇒ 1 mole of H₂O = 34 gm

so,

⇒ 10.3 mole of H₂O = 34 gm

   34 × 10.3 = 350.2 grams.

Hence, mass of 10.3 moles is 350.2 grams.
