### 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

### Re: conversion calculations

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

### Re: conversion calculations

Now calm because the mass is 7.57, the morality is 6.25 and the normality is 12.5

im doing well? :p

im doing well? :p

### Re: conversion calculations

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

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
