How do you find weight using volume?
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.
What is the density of 15 g and a volume of 2 ml?
density = mass/volume = 15g/2mL = 7.5g/mL
What is density of an object if its mass is 64 grams and the volume is 8 ml?
Density = Mass/Volume = 64 g/8 ml = 8g per ml.
What is the density for 37.72 grams of matter whose volume is 6.80 mL?
Density is mass/volume. Therefore, if you know the mass and the volume, you just do the division: 37.27 g / 6.80 ml = 5.48 g/ml
What is the density of carbon dioxide gas if 25.0 g occupies a volume of 100 mL?
Density = Mass/Volume = 25.0/100 g/mL = 0.25 g/mL
