The first step to solve this problem is to multiply the volume of solution times its concentration to find the number of moles needed, remember that M=mol/L:

Now, use the molar mass of sucrose to find the number of grams needed to make the solution. This is, multiply the number of moles needed times the molar mass:

It means that to make 0.500L of a 0.475M you will have to weigh 81.225g of sucrose.
im really sorry I need points so I’m answering this again really sorry!
Since temperature is held constant; Boyle's law can be expressed as: P 1 * V 1 = P 2 * V 2
Where P1 = 625 and V1 = 0.5 L
V2 = 925 * 10^(-3) = 0.925 L and P2 = ?
So P2 = (P1 * V1)/P2
P2 = (625 * 0.5)/0.925
P2 = 337.83 my hg
