a solution weighs 44grams. this sample contains 12grams of salt calculate % m/m salt.
(12/44)*100 = ??
To calculate the percent mass/mass (% m/m) of salt in the solution, you need to divide the mass of the salt by the total mass of the solution and then multiply by 100.
Given that the solution weighs 44 grams and contains 12 grams of salt, you can calculate the % m/m salt as follows:
% m/m salt = (mass of salt / mass of solution) * 100
% m/m salt = (12 grams / 44 grams) * 100
% m/m salt = 0.2727 * 100
% m/m salt = 27.27%
Therefore, the % m/m salt in the solution is 27.27%.
To calculate the mass percentage of salt in the solution, you need to divide the mass of the salt by the mass of the entire solution, and then multiply by 100.
The given sample contains 12 grams of salt, and the entire solution weighs 44 grams.
So, the mass percentage of salt (% m/m salt) can be calculated as follows:
% m/m salt = (mass of salt / mass of solution) x 100
% m/m salt = (12 grams / 44 grams) x 100
% m/m salt ≈ 27.27%
Therefore, the mass percentage of salt in the solution is approximately 27.27%.
