To find the number of moles of rice grains equivalent to 1.807 x 10^23 grains, you can use Avogadro's number, which is approximately 6.022 x 10^23 grains per mole. By dividing the number of rice grains by Avogadro's number, you get:

( \text{Moles} = \frac{1.807 \times 10^{23}}{6.022 \times 10^{23}} \approx 0.300 ) moles.

Thus, 1.807 x 10^23 grains of rice is approximately 0.300 moles.
