July 28, 2021 | education|
To determine the mass fraction in the composition of the compound, it is necessary to calculate the molar mass:
M (KSPO3) = M (K) + M (S) + M (P) + M (O) = 39 + 32 + 31 + 16 • 3 = 150 g / mol.
The formula for calculating the percentage of potassium in the KSPO3 compound:
W (K) = M (K) / M (KSPO3) • 100% = 39/150 • 100% = 26%
