Chemistry, need answer ASAP!! 50 points and i'll mark brainliest if correct! ^w^ How many grams are in 2.34 moles of beryllium iodide, BeI2?

615 g

Explanation:

In order to convert from moles of any given substance into grams, we have to use said substance's molar mass, as follows:

Thus, we now calculate the molar mass of beryllium iodide, BeI₂, using the molar masses of the elements:

Finally we calculate how many grams are there in 2.34 moles of BeI₂:

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
