2. Divide the mass of the solute by the total mass of the solution.1. 450g flour and 1 liter of sugar2. 500ml alcohol and 1 liter of water3. 300g rice grains and 540 ml water4. 450g sugar and 360 ml coconut milk5. 50ml liquid detergent and 250ml water
Answer:
2.95518776E−21
Explanation:
i divided them 1 by 1 and resolve all and solve to gather all mathematical information of dividing this mathematical approach so the following numbers i calculated in a calculator wasn't right so i solved them in that process GODBLES YOU CAN DO IT!
3. • At q°C, pure water has a density of Ig/mL (1 g/cm³). Stappose that have 2 liters of water at this temparature what is the you this water pure mass with solve
Answer:
Assuming you meant "pure mass" instead of "you this water pure mass", we can use the following formula to calculate the pure mass of the water:
Pure Mass = Density x Volume
Given that the density of pure water at q°C is 1 g/cm³ and the volume of water is 2 liters (which is equivalent to 2000 mL), we can substitute these values into the formula to get:
Pure Mass = 1 g/cm³ x 2000 mL
Pure Mass = 2000 g
Therefore, the pure mass of the 2 liters of water at q°C is 2000 grams.

24. DETERMINATION OF DENSITIES DISCUSSION :The density of an object is defined as its mass per unit volume. Mathematically it can be expressed as: Formula : D= M/V Where : D= density , M= mass , V= volume This usually expressed as grams per millilter (g/ml ) for liquids , grams per cubic centimeter (g/cm3) for solid , and grams per Liter (g/L) for gases.I. OBJECTIVES : After completing the activity , you should be able to:1. Learn the proper technique in measuring the mass and the volume ;2. Determine the densities of some solids and liquids , and3. Apply the rules of significant figures when reporting the weight, volume and density of each material. II- INSTRUCTION :1.0 DENSITY OF LIQUIDS:1.1 Density of water To determine the density of water , first is to get the mass of the water based from the given value below by obtaining the difference from the mass of empty cylinder and mass of the graduated and water . Assume that the volume of water is 40 ml . Compute its density .1.2 Density of colored liquid (KMnO4)To determine the density of KMnO4 , first is to get the mass of the liquid based from the given value below, by obtaining the difference from the mass of empty cylinder and mass of the graduated and KMnO4 . Assume that the volume of KMnO4 is 5 ml . Compute its density .2. 0 Density of Solids2.1 Density of regulary shaped solid The mass of the wood is already given , determine the volume of the block of wood by following the formula below. Volume of the block of wood = LXWXH Compute its density .2.2 Density of the Irregularly shaped solid ( green jade sample ) To get the volume of the irregularly shaped solid, perform using the water displacement method. Compute the density by using the given value for the mass . II.
