How many hydrogen ions are in 1 liter of stomach acid? (hint: avogadro’s number). show your work and remember to put your answer in regular number form (not scientific notation).

1 200 000 000 000 000 000 000 000 H⁺ ions

Step-by-step explanation:

Assume that the concentration of H⁺ ions in stomach ions is 2.0 mol·L⁻¹.

Then, we have 2.0 mol of H⁺ ions

There are 6.02 × 10²³ H⁺ ions in 1 mol.

2.0 mol = 2.0 × 6.022 × 10²³/1

             = 1.2 × 10²⁴ H⁺ ions

             = 1 200 000 000 000 000 000 000 000 H⁺ ions

answer: i would say b.

explanation:

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
