Step-by-step explanation:
Data
Volume = 250 ml
moles of sucrose = 0.15 mol
Molarity = ?
Formula

Process
1.- Convert 250 ml to liters using proportions
1000 ml ----------------- 1 l
250 ml ---------------- x
x = (250 x 1 ) / 1000
x = 250 / 1000
x = 0.25 l
2.- Substitute values in the formula

3.- Simplification and result
Molarity = 0.6
