In chemistry, a mole is a quantity used relate reactants to products in stoichiometric equations. A mole of any substance is equal to 6.02 x 10^23 particles -- usually atoms or molecules -- of that substance. For a given element, the mass (in grams) of o

How to Find Molarity As long as you have a way of measuring the mass of a solute, you can calculate its molarity by measuring the volume of the solution. Be careful here, because molarity is always expressed as moles/liter, so if you measure volume in any other units, you have to con...
How do you find moles in chemistry if you have grams? Calculate the number of grams present in 11.42 moles H_2O? Determine the mass in a sample of 3.2 moles of Ga. Calculate the number of moles corresponding to 8.3 g H_2. Calculate the number of moles corresponding to 4.9 g F_2....
Find the number of grams in 0.700 moles of hydrogen peroxide, H2O2. Solution Calculate the molar mass by multiplying the number of atoms of each element in the compound (its subscript) times the atomic mass of the element from the periodic table. ...
First, begin by converting millimolar to molar: (10 mmol MgCl2/1 L)x(1 mol/1000 mmol) = 0.010 mol MgCl2/1 L. Next, you can use the molar mass to find how many grams of MgCl2 there are in 0.010 moles or MgCl2: (0.010 mol MgCl2/1 L)x(96.211 g MgCl2/1 mol MgCl2) = 0.962 g...

How to find Median To find the median, simply line up all your numbers from smallest to biggest, and then pick the one right in the middle. But here comes the tricky part. If you have an odd number set, the median is just the one in the middle. However, if you have an even numb...
