a) 0.278 g
b) 0.278 kg
c) 0.278 mg
d) 0.278 cg

Answer 1

The mass of 0.278 ml of water is 0.278 g, as the density of water is 1.0 g/mL and mass is calculated by multiplying density by volume.

Step-by-step explanation:

The mass of 0.278 ml of water can be calculated by using the density of water. Since the density of water is approximately 1.0 g/mL, the mass of 0.278 mL of water is simply 0.278 g/mL multiplied by the volume of water which gives us: 0.278 g/mL × 0.278 mL = 0.278 g.
