At first sight translation process of milliliters in grams can be necessary only when performing tasks on some disciplines, for example, in physics for mathematics or chemistry. However in practice such actions can quite be useful even to the housewife in kitchen. Often in the offered compounding of dishes the same ingredients are given in milliliters, in grams. So, skills of this sort will be able really to be useful.
It is required to you
- - Table of density of substances;
- - calculator.
Instruction
1. There is a formula which connects among themselves three characteristics: volume, weight and density: m = rVOboznacheniya for these parameters have an appearance: V – volume, mlm – weight, gr – density, g/ml the simplest example it is possible to consider calculations with water which has the constant density equal to 1 g/ml.
2. Example No. 1. Calculate the mass of water if its volume is 500 ml. Write down formula m = rVPodstavte the values given in a condition: m (water) = 1 g/ml x 500 ml = 500 g
3. In the same way it is possible to transfer milliliters to grams not only for water, but also other substances. The main thing at the same time to know values of density which are a reference material. They can be found in textbooks by physics, chemistry or on the Internet. Besides sometimes volume can be given not in milliliters, and in liters, in cubic centimeters or meters. In this case the offered data need to be translated in milliliters, and then to carry out further calculations.
4. Example No. 2. Calculate the mass of vegetable oil if its volume is 200 ml. Density of vegetable oils of different types varies within 0.87-0.98 g/cm3 or 0.87-0.98 g/ml. If the concrete size of density of oil is known, then it is easy to calculate weight. For example, density is 0.93 g/ml. Substitute this value in formula m = pVm (oil) = 0.93 g/ml x 200 ml = 186 g
5. In case of need on the same formula it is possible to execute also the return recalculation, that is to transfer grams to milliliters. Example No. 3. Calculate water volume if its weight is 500 g. Write down formula m = rVVyvedite from it the volume of V = m/VPodstavte offered in a value condition: V (waters) = 500 g / 1 g/ml = 500 ml
