Write the correct molecular formula, then calculate the molecular mass and the percent composition for potassium nitrate (also known as saltpeter). Please show one or two decimal places for \% composition answers. Formula If this compound dissolves in water, what is the total number of ions (positive and negative) that will be formed according to the formula? (fill in the number - 1, 2, 3, etc.) Molecular Mass \( \quad a m u \) \( \% \mathrm{~K} \) \( \% \mathrm{~N} \) \( \% \mathrm{O} \) Note: \( \mathrm{K}=39.098 \mathrm{amu} ; \mathrm{N}=14.007 \mathrm{amu} ; \mathrm{O}=15.9994 \mathrm{amu} \)
