Density is the amount of mass per given volume, thus the formula for density of an object with a known mass and volume is as follows:
ρ=m/V where:
ρ - (rho) Density (Kg m-3)
m - Mass (Kg)
V - Volume (m3)

How do you find mass of a solute when cubic centimeters and molarity is given?
To find the mass of the solute, you first need to calculate the volume of the solution using the given cubic centimeters. Then, use the formula: mass = volume (in liters) x molarity x molar mass of the solute. Convert cubic centimeters to liters before calculating.
How do you find molecular mass if specific volume is given?
To find the molecular mass if specific volume is given, you can use the ideal gas law. The ideal gas law relates the pressure, volume, temperature, and the number of moles of gas to the gas constant. By rearranging the ideal gas law equation and solving for the molecular mass, you can determine the molecular mass of the gas.
The mass of solute in a given volume of solution or mass volume?
The concentration of a solution can be expressed in terms of mass/volume or mass/mass ratios. Mass/volume concentration is calculated by dividing the mass of the solute by the volume of the solution. This measurement is often used in chemistry and medicine to determine the amount of solute present in a specified volume of solution.
How do you calculate the moles of water?
To calculate the moles of water, you can use the formula: moles = mass of water (in grams) / molar mass of water (about 18.015 g/mol). Simply divide the mass of water by its molar mass to find the number of moles.
How do you find no of atoms if molar mass and density is given?
To find the number of atoms from molar mass and density, you can calculate the number of moles using the molar mass and then use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms. First, calculate the number of moles by dividing the given mass by the molar mass. Then, multiply the number of moles by Avogadro's number to find the number of atoms.
How do you find mass of a solute when cubic centimeters and molarity is given?
To find the mass of the solute, you first need to calculate the volume of the solution using the given cubic centimeters. Then, use the formula: mass = volume (in liters) x molarity x molar mass of the solute. Convert cubic centimeters to liters before calculating.
The volume in ml of 2.26m potassium hydroxide solution that contains 8.42g of solute?
To find the volume of 2.26M potassium hydroxide solution that contains 8.42g of solute, you can use the formula: moles = mass / molar mass. First, calculate the moles of solute using the given mass and molar mass of potassium hydroxide. Then, use the molarity (2.26M) to find the volume of the solution using the formula: volume = moles / molarity.
How do you find moles of hydrogen?
To find the moles of hydrogen, you can divide the given mass of hydrogen by its molar mass. The molar mass of hydrogen is approximately 1 g/mol. So, moles of hydrogen = mass of hydrogen (in grams) / molar mass of hydrogen (approximately 1 g/mol).
How many liters of a 1.5M solution are required to yield 5.0 grams of solute?
To find the volume of solution needed, you can use the formula: ( \text{moles} = \text{mass} / \text{molar mass} ). Given the mass of the solute (5.0g) and the concentration of the solution (1.5M), you can calculate the moles of solute. Then use the molarity equation to find the volume in liters: ( \text{Molarity (M)} = \text{moles} / \text{volume (L)} ).
How does on find mass when given density and volume?
Multiply them: density*volume = mass
How do you find molecular mass if specific volume is given?
To find the molecular mass if specific volume is given, you can use the ideal gas law. The ideal gas law relates the pressure, volume, temperature, and the number of moles of gas to the gas constant. By rearranging the ideal gas law equation and solving for the molecular mass, you can determine the molecular mass of the gas.
How do you find the mass of an object when given the volume?
Volume = mass / density
The mass of solute in a given volume of solution or mass volume?
The concentration of a solution can be expressed in terms of mass/volume or mass/mass ratios. Mass/volume concentration is calculated by dividing the mass of the solute by the volume of the solution. This measurement is often used in chemistry and medicine to determine the amount of solute present in a specified volume of solution.
How do you find the mass of an object when you are given the volume and density of the object?
You can find the mass of an object by multiplying its volume by its density. The formula to calculate mass is: mass = volume x density. Simply plug in the given values for volume and density to calculate the mass of the object.
How do you calculate the moles of water?
To calculate the moles of water, you can use the formula: moles = mass of water (in grams) / molar mass of water (about 18.015 g/mol). Simply divide the mass of water by its molar mass to find the number of moles.
How do you find moles of a chemical with density and molar mass?
You need also to know the volume or the mass of the sample.
How can I find the mass if only the volume and density are given?
Density = (mass) divided by (volume)Mass = (Density) times (volume)
