# How do you convert grams per centimeter cibe to grams per moles?

Answer .
So in order to answer this question you need to know the molecular weight of the substance in question. grams per mole is the same as the molecular weight for a simple compound..
For example, water is approximately 18.016 grams per mole because oxygen's atomic weight is 16.00 and hydro…gen, 1.008, approx. Water is one oxygen and two hydrogens, so add that all up and you get 18.016, again approximate. A mole is "Avagadro's number" of something. This is a really big number but the point of this number is that this is the number of hydrogen atoms (1st isotope) that make up a gram of hydrogen. ( Full Answer )

# How do you convert moles into grams?

II. CHANGING NUMBER OF MOLES TO MASS .
If we are given the number of moles of a substance, we can convert that into a mass, based on our knowledge of Molar mass. We can use the formula from the section above, and adjust it for the new unknown, which will be mass of the sample:.
mass of the sample… # of moles of the substance = --------------------------- Molar mass of substance.
To isolate the mass of the sample, we must multiply both sides by Molar mass of a substance:.
mass of the sample x Molar mass of substance # of moles of the substance x Molar mass of substance = --------------------------- Molar mass of substance .
So we are left with the formula:.
mass of the sample = # of moles of the substance x Molar mass of the substance..
Example 1. A certain laboratory procedure requires the use of 0.100 moles of magnesium. How many grams of magnesium would you mass out on the balance?Solution, from the period table we get the Molar mass of magnesium as 24.3 g. We then place that information in the formula below:mass of the sample = # of moles of the substance x Molar mass of the substance.Given: The # of moles of the substance = 0.100 mol The Molar mass of the substance = 24.3 g/molmass of the sample = 0.100 mol of magnesium x 24.3 g/ mol .
