This looks, at first glance, a homework dump. You need to show SOME effort and I see none. At least tell us what you don't understand and how we can help. Also, you might include how you think the problem should be approached.
M = mols/L. You know M and L, solve for mols.
mols = grams/molar mass. You kow molar mass and mols, solve for grams.
Post your work if you get stuck.
