A chemist adds 975.0 mL of a 0.00988 g/L magnesium fluoride (MgF2) solution to a flask. Calculate the mass in grams of magnesium fluoride the chemist has added to the flask. Round your answer to 3 significant digits. x 5 ?

Answer 1

First Answer: into L convert volume mit 10oomL = 1L in 1 mL - I L 1000 = 0.9752 in 975.0mL = 975 1000 density (d) = mass (m) Volume (V) so mass (m) - density (a) x Volume) = 0.00988 g x 0.975K L = 0.0096339 - 963x105 g mars of magnesium Fluoride (MgF2) = 963810-S "Please rade it"
