chemistry help!gram molecular mass?

so i need to find the gmm of .0688g AgCl.i know how to do everything.my only problem is rounding the numbers.i have to round it to the nearest tenth.so aluminum is 26.98154.and i know that if i round it,it's gonna be 27.for chlorine it's 35.4527.so i don't know if it's supposed to be 35.5 or 36.also i don't know what nickel is.it's 58.6934,would it be 58.7 or 59??please help me!i'm really confused

Answer:

just because you're rounding does not mean that 0 for AL isn't importantMy suggestion is to use all the numbers and just round it AFTER all the calculations have been completed and you have the final answerGood luck with the problem and hope this helps!! )
