What is the mole fraction of oxygen in a gas mixture that is 37 percent oxygen and 63 percent nitrogen in volume? To find the mole fraction of oxygen, first convert the percentages to fractions ...
The amount of water which needs to be added then simply follows from: Ma = Mt - M0 = 1000000 - 100 = 999900 gram water. Calculate the required volume of 65% HNO3 needed to make the solution ...
Percent abundance is a measure of how much of a particular isotope is present compared to the other isotopes of the same element. It provides information about the distribution of isotopes in a ...
percent is just another way of saying "out of 100". So 85% is 85 out of 100, or as a fraction 85/100. That can then be simplified by a factor of 5 to give 17/20.
To make a 10% solution from a 20% solution, you can mix equal volumes of the 20% solution with water. For example, to make 1 liter of 10% solution, mix 500 ml of the 20% solution with 500 ml of ...
The mole fraction of HCl in a 20% aqueous solution can be calculated by converting the percentage to a molarity concentration. Assuming the density of the solution is 1 g/mL, a 20% solution means ...
Population of the World: 6,775,235,700. terrible English is instead of are. Approximately 20.25% of the world's population. Approximately 16% of the global population is white. it is estimated ...
