How many moles are in 765 grams of {eq}C_2H_6O {/eq}?MolesThe moles of a substance is equal to the ratio of the mass of the substance to its molar mass. For example, the number of moles of 10.0 g of NaOH can be
See examples of how to find moles from grams. Related to this QuestionHow many moles of water are there in 100 grams of water? What is the mass, in grams, of 1.24 mol of water? If a sample of water contains 4.568 \times 10^{25} atoms, how many grams...
Find the molecular weight of each atom in the substance. The molecular weight is how much each molecule of the substance weighs and is given in grams over moles. The weight for any atom is on a periodical table under that listing of atoms. Step 3 Find the total molecular weight of the ...
Sometimes you're given a value inmolesand need to convert it to grams. To do this, first calculate the molar mass of a sample. Then, multiply it by the number of moles to get an answer in grams: grams of sample = (molar mass) x (moles) Problem Find the number of grams in 0.700...

Moles and Equivalents The equivalent unit was introduced to account for the fact that when solutes dissolve in solvent to create a solution, the number of particles dispersed depends on the valence of the solute. For example, when one molecule of KCl dissolves, it leaves two ions, or charged...
Calculating the Mass of a Substance in a Mixture Step 1: Identify the components of the mixture. Step 2: Find the percentage of the desired component present in the mixture. Step 3: Find the total mass of the mixture. Step 4: Multiply the percentage of the desired component with the tota...
A solution may contain billions upon billions of particles, so chemists, for convenience, specify the amount of solute in terms of moles. Each mole contains 6.022 × 10^23 particles, and the mass of a mole of particles is the sum of the atomic weights of its elements. To find the ...
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...
