Please help me!!! 1. Convert 4mols H20 to grams?

а 72g
b 92g
c 83g
d 62g

2. Convert 4mols of H2O to atoms of H2O?

a 1.4 x 10^24 atoms H2O
b 4.1 x 10^24 atoms H2O
c 3.3 x 10^24 atoms H2O
d 2.4 x 10^24 atoms H2O

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.

diaria maybe go see a doctor about that
