Answer:
Destiny = 5 g/ml
Explanation:
The formula for density is d=
Knowing this, divide your mass by volume:
10 g / 2 ml = 5 g/ml
Final answer:
Destiny = 5 g/ml
Explanation:
If a gas were to be heated up the pressure does not change, but the volume it will.
For a fixed mass or gas at constant pressure is volume ÷ temperature stays the same.
