To find this you also need to know the chemical (or formula) weight of one mole of the compound in grams per mole (so about which compound you're talking about).

To find the molarity of a solution, you first need to calculate the mass of the solute using the percentage mass and density. Then, convert the mass of the solute to moles using its molar mass. Finally, divide the number of moles of solute by the volume of the solution in liters to find the molarity.

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.
What is the molarity of a solution which contains 2 moles of glycerin dissolved in 1000g of water?
To find the molarity, first calculate the molar mass of glycerin to be 92.1 g/mol. Next, convert 1000g of water to liters by dividing by the density of water (1g/mL). Calculate the moles of glycerin in the solution. Finally, divide the moles of glycerin by the volume of the solution in liters to find the molarity.
How do you find the mass of water if only density is given?
you weigh the water
If you were given the molarity and volume of the acid and the volume of the base what additional step is needed to calculate the molarity of the base?
To calculate the molarity of the base, you would use the formula for dilution: M1V1 = M2V2, where M1 is the molarity of the acid, V1 is the volume of the acid, M2 is the molarity of the base (what you're solving for), and V2 is the volume of the base. Rearrange the formula to solve for M2, the molarity of the base.
What is the molality of a solution of ZnSO4 whose density is 1.25 g per ml and whose molarity is 1.19M?
To find the molality of the ZnSO4 solution, we first need to calculate the molar mass of ZnSO4, which is 161.47 g/mol. Next, we convert the density to kg/L (1.25 g/ml = 1.25 kg/L). Finally, we use the formula: molality = (molarity * molar mass) / (1000 * density in kg/L) to find the molality, which is approximately 1.51 mol/kg.
What is molarity of a solution made by dissolving 2 moles of NaOH in 6 kg of water?
To find the molarity, we first need to convert the mass of water to volume using the density of water. Given the density of water is approximately 1000 g/L, 6 kg of water is equivalent to 6000 g or 6 L. Next, calculate the molarity using the formula Molarity (M) = moles of solute / liters of solution. In this case, 2 moles of NaOH in 6 L of water gives a molarity of 0.33 M.
How can you determine molarity from percent purity of solution?
To determine the molarity from percent purity of a solution, you need to know the mass of the pure solute in the solution. You can calculate this by multiplying the percent purity by the total mass of the solution. Then, you can use this mass to calculate the molarity by dividing it by the molar mass of the solute and the volume of the solution.
How do you find density if mass and density are given?
Strictly speaking if the density is given then you don't need to find it.
What is the molarity of 35 per cent Hydrochloric acid solution with specific gravity of 1.8 gram per liter?
To find the molarity, we first need to calculate the weight percent of hydrochloric acid in the solution: 35% of the solution is HCl. Then we calculate the molarity using the specific gravity, which is the ratio of the density of the solution to the density of water. Finally, we use the molarity formula to find the molarity: Molarity = (Weight % HCl / molar mass of HCl) / (Specific gravity of the solution).
A solution is prepared by dissolving 16.2 g of benzene in 282 g CCL4 find molarity of thesolution density of the solution is 0.92gml?
To find the molarity of the solution, first calculate the total mass of the solution by adding the mass of benzene and CCl4. Then, use the density of the solution to convert the mass to volume. Finally, calculate the molarity using the formula: Molarity = moles of solute / volume of solution in liters.

What is the molarity of a solution which contains 2 moles of glycerin dissolved in 1000g of water?
To find the molarity, first calculate the molar mass of glycerin to be 92.1 g/mol. Next, convert 1000g of water to liters by dividing by the density of water (1g/mL). Calculate the moles of glycerin in the solution. Finally, divide the moles of glycerin by the volume of the solution in liters to find the molarity.
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.
