How much is 500ml in grams please.?

In order to find out how many grams is in 500ml, one must have a measurement of density available. If density is not known, it can be found by finding the volume of the substance in ml, finding mass in grams, and dividing mass by volume. From there, multiply the result by 500ml to find the amount of grams in 500ml of the substance.


What is the mass of ethanol dissolved in one liter of a 6.8 percent ethanol solution?

To find the mass of ethanol in a 6.8% ethanol solution, you would first need to calculate the volume of ethanol present in the solution. For a 6.8% solution, this would be 0.068 liters of ethanol. Next, you can use the density of ethanol (0.789 g/ml) to convert the volume to mass, which would be 0.068 liters * 0.789 g/ml = 0.0536 g of ethanol in one liter of the solution.
