The number of L present in a 10.0 lb sample of a substance with a density of 0.25 g/cm³ is 1.8L.
The volume of a substance can be calculated by dividing the mass by its density as follows:
Volume = mass (g) ÷ density (g/cm³)
According to this question, 10.0 lb sample of a substance has a density of 0.25 g/cm³. The volume can be calculated as follows:
10.0 Ib to grams = 453.59 grams
1 gram/cubic centimetre = 1000 grams/Litre
0.25g/cm³ = 250g/L
Volume of substance = 453.59g ÷ 250g/L
Volume = 1.8L
Therefore, the number of L present in a 10.0 lb sample of a substance with a density of 0.25 g/cm³ is 1.8L.
