WILL GIVE BRAINLIEST AND 20 POINTS! How many grams of K2Cr2O7 does a 1-L 2.16 M solutions contain in a 350-mL solution? (molar mass = 294.2 g/mol)

14g CH3OH X  

1molCH3OH

32.0g = 0.44 mol CH3OH

100.0g H2O X 1Kg

103g = 0.1000 Kg H2O

m =  

0.44mol CH3OH

0.1000Kg H2O = 4.4 m

Explanation: I THINK THAT IS THE ANSWER

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.

i'm pretty sure its b i might be wrong though!
