About the same density as water. In cottage cheese 500 ml is very close to 500 grams
The density of water is pretty close to 1 g / mL across the range of temperatures that it is a liquid. So 500 g / (1 g/mL) = 500 mL = 0.5 liter
500 g/mL
The weight of 500 ml of caramel depends on its density, but caramel typically has a density of about 1.2 grams per milliliter. Therefore, 500 ml of caramel would weigh approximately 600 grams (500 ml x 1.2 g/ml = 600 g).
500 cc's of hydrogen peroxide is equivalent to 500 milliliters. Hydrogen peroxide has a density of 1.5 g/ml, so 500 ml would weigh approximately 750 grams.
The density would be 25/500 =0.05 g/mL This is a totally unlikely result since the rock has roughly one twentieth the density of water!
Lead has a density of approximately 11.3 g/mL, so it does not have a density of 5 g/mL. Copper has a density of 8.96 g/mL, which is closer to 5 g/mL but not exactly the same.
If you know the volume of something you can find its weight (or mass) if you know it's density. Density is a measure of a substances mass per unit volume. So for example; Q: How much does 0.5 litres of water weigh? A: The density of water is roughly 1 gram per cm3. A cm3 is the same as a mL (millilitre), and there are 500 mL in a 0.5 litres. So, weight = 1 g/mL * 500 mL = 500 g You can find densities of various substances on the internet or in reference texts.
400/500=0.8g/cc
Does not convert; milligrams (mg) and grams (g) are measures of weight or mass and mL (milliliters) is a measure of volume.
This is not a valid conversion; milligrams (mg) and grams (g) are measures of weight or mass and mL (milliliters) is a measure of volume.
Milliliter(ml) is a unit of volume and gram(g) is a unit of mass. Since both quantities are different so we can't relate these two directly. So there is no way by which relation can be formed between these two. However there is one way by which these can be relate: by introduction of another term which is 'density'. Density(ρ), as we know, is equal to Mass(M)/Volume(V). And Mass, from the above relation, can written as V x ρ, i.e. M = V x ρ Putting M = 125 g and V = 250 ml, we get: 125 = 250 x ρ ρ = 125/250 g/ml = 0.5 g/ml So 125 g is equal to 250 ml only if density of the substance is 0.5 g/ml.
