New here and need some help on this chem problem

Its probably really easy but im having problems- you have 500 ml solution of water with NaOH 0,1 mol/L(solution A), 10 ml of solution A is taken and put in another glass filled with water so that it can become a new 100 ml solution.(solution B)

How much NaOH moles are in A

How much grams of Naoh are used for making A

What is the concentration (mol/L) of solution B.

What equations do you know of involving moles and concentration? Hint: look at the units.

Have you covered dilution calculations in class?
