To convert milliliters (mL) to kilograms (kg), you need to know the density of the substance in question. The density of a substance is its mass per unit volume. For water, which has a density of 1 g/mL, 7500 mL would be equal to 7500 grams. To convert grams to kilograms, you divide by 1000, so 7500 grams is equal to 7.5 kg.

Without knowing the density of the substance
7500 ml is a measure of VOLUME. and 'kg' is a measure of MASS.
This is not a valid conversion; kilograms (kg) and grams (g) are measures of weight or mass while milliliters (mL or ml) measure volume.
This is not a valid conversion; kilograms (kg) and grams (g) are measures of weight or mass while milliliters (mL or ml) measure volume.
The density is 10 kg/mL
density = mass / volume → density_ball = 2kg / 6ml = 1/3 kg/ml ≈ 0.333 kg/ml If you want it in other units: 1 ml = 1 cm³ → density ≈ 0.333 kg/cm³ 1 kg = 1000 g → density ≈ 333 g/cm³ 1 m³ = 1000000 cm³ → density ≈ 333,333 kg/m³ That is one dense material of which the ball has been made (mercury has a density of 13,594 kg/m³, so the material is about 25 times denser than mercury) - have you got your units correct?
1.75% of 7500= 1.75% * 7500= 0.0175 * 7500= 131.25
This cannot be sensibly answered. A milliliter (mL or ml) is a measure of volume, kilograms is a measure of weight or mass.Millilitres, mL, are a measure of volume, whereas kilograms, kg, are a measure of mass.As such, the two cannot really be compared.However, one litre of weighs exactly one kilogram, so one could say that there are 1000 mL in 1 kg of water.
