physical properties
Explanation:
temperature, volume and colour are all physical properties
To convert moles to gram multiply 3.7 moles of BaF2 to the molar mass of BaF2
BaF2 molar mass = 175.326
3.7 moles x 175.326g = 648.70g BaF2
Answer:
Since I already answered the first two I will tell you the third one!
