Answer:
101.965ml
Explanation:
Density is the mass of an object compared to its volume. It described by the formula D = m/v, so so mass and density and directly proportional and volume and density are inversely proportional. To find the volume given the density and mass, shift the formula by changing the spot of D and v, so v = m/D.
m = 80.45g
D = 0.789g/ml
v = 80.45g/0.789g/ml = 101.965ml
If you wanted to find the mass given the volume and density you would multiply v and D
D = m/v
vD = m
