crystal​

Answer 1

Answer:

lol. hi . good question. mark my answer brainliest and verify it as 'verified answer'

Explanation:

molar mass of CuSO4.5H2O= 249.72g/ mole

no .of moles = given mass/ molar mass

no. of moles = 499/249.72g

so , no. of moles = 1.998 moles (ANSWER FOR FIRST PART OF YOUR QUESTION)

AND NOW(TAKE THIS IMPORATANTLY)

IF, you are doing this sum for school exams, you should round of the no.of moles to 2 for calculation purposes

OR,

if you are doing for practice then take it 1.998 or 2 for curiosity purposes
