Please help with this question, I can't figure out how to calculate how much yield of sodium selenite is produced.

Here's the question :
A teacher reacted 5g of selenium oxide and expected to obtain 7.785g of sodium selenite. Using the results below, calculate the percentage yield of the product

Mass of crucible (g) = 24.85

Mass of crucible and selenium dioxide before heating (g) = 29.85

Mass of crucible and sodium selenite after heating (g) = 31.195

Btw here's the formula for this reaction : SeO2 + 2NaOH > Na2SeO3 + H2O (The numbers which come after elements are meant to be small and show the number of atoms)

Thank you!

Basically actual mass / theoretical mass X 100
So 31.195 /
What he expected which was : 7.785
X 100
Idek about the numbers but the equation is actual / theoretical x 100
