The mass is 40 g.
Density is the mass per unit of volume of a substance. The equation to calculate density is:
density = mass/volume
In this question, you are given the density and the volume of a substance, and requires you to determine the mass.
Rearranging the density formula:
mass = density x volume
mass = 2 g/mL x 20 mL = 40 g
It depends on the density of the liquid.
Problem: You are given two unknown liquids. Find the density of each. Materials: 100ml graduated cylinder, triple beam balance, calculator, 2 unknown liquids. Procedure: 1) Find the mass of the empty graduated cylinder. 2) Pour unknown liquid #1 into the graduated cylinder to the 50 ml. level. 3) Find the mass of the graduated cylinder with 50ml of unknown liquid #1. 4) Repeat steps 1-3 for unknown liquid #2. We can calculate density of a liquid using the formula: Density= Mass/Volume where mass is that for just the liquid (you must subtract out the mass of the graduated cylinder). Now let's calculate the densities of the two liquids using the following given data. Liquid #1: Given: Mass of empty graduated cylinder = 78 grams Mass of graduated cylinder with unknown liquid #1= 128 grams. Find: a) Mass of just the liquid = ____ b) Volume of liquid=_____ c) Density of liquid #1 =____ Liquid #2: Given: Mass of empty graduated cylinder = 78 grams Mass of graduated cylinder with unknown liquid #2= 117.5 grams. Find: a) Mass of just the liquid = ____ b) Volume of liquid =_____ c) Density of liquid #2=____ Check your answers by inserting the value in the box below.
i think its 50 grams ------------------------------------------------------------ The cup is a unit of volume and the gram is a unit of mass; they are not comptible. For an answer you need to know the density because: mass = volume x density
Answer Increasing the volume of a quantity while keeping its mass fixed decreases its density (mathematically, d = m/v). This can be observed in the transition of water from its liquid stage to its solid stage, or vice versa. As water turns into ice, its volume increases yet its mass is fixed (no additional water is added or lost--assuming the losses from evaporation is negligible); hence its density will decrease. This is why ice cubes float in drinks, or icebergs exist. drugs are bad mmkay!!!!!
Density = Mass/Volume So Volume = Mass/Density = 45.6g / 10.5 g per ml = 45.6/10.5 ml = 4.34 ml (to 2 dp)
This is not a proper conversion. Cubic centimeters (cc) is a measure of volume. Grams (g), kilograms (kg) and milligrams (mg) are measures of weight or mass.

Density = Mass/Volume = 30/15 = 2 grams per millilitre.
Density = Mass/Volume = 21g/2cm3 = 10.5 grams per cm3
density = mass/volume = 2g/40cm3 = 0.05g/cm3
i think its 50 grams ------------------------------------------------------------ The cup is a unit of volume and the gram is a unit of mass; they are not comptible. For an answer you need to know the density because: mass = volume x density
density = mass / volume = 72 g / 36 cm³ = 2 g/cm³
density = mass/volume volume = 2cm x 2cm x 2cm = 8 cm^3 density = 16 grams / 8 cm^3 = 2 grams/cm^3

2 g/cm3. This can be done by using the formula for density (mass/volume) and conversion 1mL=1cm3 The density of that liquid is 2.
Density = Mass/Volume = 30/15 = 2 grams per mL.
Density = mass/volume Density of the cube = 8g/2cm3 = 4g/cm3
