Calculate the molarity, normality and molality of a 32% H 2 CO 3 solution with a density of 1.18g / ml.      ### Re: conversion calculation

Calculate the mass of one 1l . 32% is the mass of the 100% carbonic acid. Convert this with molar mass to mole. The rest should be easy now

I expect instead of mmmmmm, that you post your calculation or the result.

Now calm because the mass is 7.57, the morality is 6.25 and the normality is 12.5
im doing well? :p

What is 7.57 eggs because of easter?

1 l= 1.18 kg
32% is 377,6 g = m

n =m/M 377,6 g/ 62 g/mol = 6,09 mol = Molarity
Normality is double = 12,18 mol
