It depends on if they are solid or liquid.

Both 1 kg of feathers and 1 kg of lead have the same mass, which is 1 kilogram. However, feathers have a much lower density than lead, meaning that 1 kg of feathers will occupy a significantly greater volume than 1 kg of lead. Therefore, 1 kg of feathers has a greater volume than 1 kg of lead.
1 millilitre of water at sea level and 1degree centigrade will be one gram in mass. Other substances may vary in their mass. A milliltre is a measure of volume. Therefore, a more dense sustance (lead for example) will have a greater mass than a less dense one (for example air). It is usual to measure liquids in milliltres, solids tend to be measured by mass.
The volume of lead will be less than one gram of water. Lead is denser than water, so it takes up less space for the same mass.
aluminium
This depends on the mass.
water has less density than lead. Mass depends on its volume
Lead sinks in water due to its high density, which is greater than the density of water. This causes it to displace a smaller volume of water compared to its own volume, resulting in it sinking.
Converting grams to milliliters depends on the density of the substance. To convert, you need to know the density of the substance in grams per milliliter. Then you can use the formula: volume (in milliliters) = mass (in grams) / density (in grams per milliliter).
It depends on if they are solid or liquid.
Lead (11,34 g.cm^-3) has a greater density than water (1 g.cm^-3) so for the same volume of water and lead, lead will be heavier. The "-3" should be written as an exponent but it won't allow me
Grams and ounces are units of weight, not volume. To convert between the two, you would need to know the density of the substance you are measuring. If you are looking to convert based on a rough estimate, you could use the fact that 1 ounce is approximately equal to 28 grams.

They both weigh the same: 1kg = 1kg. The kg of butter has a greater volume and the kg of lead has a higher density.
The density of 1 gram depends on the substance in question. Density is defined as mass divided by volume, so without knowing the volume of the substance, it is impossible to determine its density.
