We know that there is 1000 g of water per liter and it has a molar mass of 18 g, thus the water concentration is [H 2 O] = 1000/18 = 55.56 M. If we assume water concentration doesn't change we can rewrite equation 1.7 as. This new K w constant will have a value of 1.8×10 -16 ×55.56=10 -14. hancock nh public library https://departmentfortyfour.com
