Answer to Question #160825 in Chemistry for Jack R Tillman

Question

Q is a ficticious element. If the molar mass of the Q is 5.36grams/mol and you have 8.76 moles of Q, how many grams is this?

Answer 1

Solution:

Moles of Q = Mass of Q / Molar mass of Q

Hence,

Mass of Q = Moles of Q × Molar mass of Q

Mass of Q = 8.76 mol × 5.36 g/mol = 46.9536 g = 46.95 g

Answer: 46.95 grams.
