What is the percent mass of KClO3 in a mixture if the original starting material weighted 3.58(g) and the mass of KClO3 in mixture is 1.67(g)

46.65

To find the percent mass of KClO3 in the mixture, we need to divide the mass of KClO3 by the total mass of the mixture and then multiply by 100.

The mass of KClO3 in the mixture is given as 1.67 g.
The original starting material weighed 3.58 g.

To find the mass of the remaining components in the mixture, subtract the mass of KClO3 from the total mass:

Total mass of the mixture = 3.58 g - 1.67 g = 1.91 g.

Now, to find the percent mass of KClO3, we divide the mass of KClO3 (1.67 g) by the total mass of the mixture (1.91 g) and then multiply by 100:

(1.67 g / 1.91 g) x 100 = 87.43%

Therefore, the percent mass of KClO3 in the mixture is approximately 87.43%.
