A 1.8 g potato core is submerged in sugar water. When it is removed, its mass is 1.6 g. What is the percentage loss of the potato's mass? F Round your an swer to the neare st hundredth of a percent.

The percentage loss or decrease in any quantity is also calculated using somewhat the similar formula: In this problem, the old value (the initial mass of the potato core) is and the new value (the mass after submerging in sugar water) is . Plugging these amounts into the formula gives: Therefore, the percentage mass loss of the potato core is . This means the mass of the potato core decreased by after being submerged in sugar water.
