What mass in milligrams does 2.63 moles of nickel have?
The molar mass of nickel is 58.69 g/mol. To convert moles to milligrams, you need to multiply the number of moles by the molar mass and then convert grams to milligrams. So, 2.63 moles of nickel is equal to 154,766.7 milligrams.
How do you convert an element to moles?
to convert an element to moles you need to setup and equation, for our example we will be using 5g of O2 or oxygen. You need to know what O2's molar mass is as well, it is 32g. So the equation would be 5g of O2 / 32 = .16 moles of O2. So to convert moles to grams all you do is multiply the moles given by the molar mass of the element/compound and you have your grams Hoped this helped : )
What mass in mg does 2.63 moles of nickel have?
To calculate the mass of nickel in milligrams from moles: Find the molar mass of nickel from the periodic table: 58.69 g/mol. Convert moles to grams given mole quantity x molar mass. Convert grams to milligrams (1 g = 1000 mg) to find the mass in milligrams.
How is the number of moles of an element determine from a known mass?
The mass of 1 mole of the element is used as a conversion factor to convert grams to moles
How many mg in a mole?
The atomic mass of an element in grams is equal to the mass of one mole of atoms of that element. To convert from grams to milligrams, you can multiply by 1000 since there are 1000 milligrams in a gram.
How do you convert milligrams to 2.8 grams?
1000 milligrams is equal to 1 gram, therefore 2.8 grams is equal to 2800 milligrams. To convert from grams to milligrams multiply by 1000, and to convert milligrams to grams divide by 1000.
How do you convert Milligrams per liter to moles per liter?
In order to convert between milligrams and micromoles, one has to know the molar mass of the substance in question, then simply convert from grams to moles. As an example, let's assume that the measurement is that of oxygen, or O2, and that there's 10 milligrams per liter. First, divide by 1,000, to convert to grams, in this case, .01 grams. Then, divide this amount by the molar mass, which represents the number of grams in a mole. For O2, this is approximately 31.9988. This gives us a result of around .0003125 moles, or 3.125 x 10^-4. Then, we multiply by 1,000,000 to convert from moles to micromoles. The end result is approximately 312.5 micromoles in the liter.
How do you calculate milligrams of caffeine in 60 mL sample?
You have to know the concentration first. That will either be in grams per milliliter (or milligrams per milliliter), or it could be in moles per liter (molarity). If it's given in grams per milliliter, just multiply that number by 60 and multiply by 1000.If it's given in moles per liter, than first find how many moles in 60 mL by multiplying by 0.06, and then convert moles to grams using the molar mass of caffeine (194.19 grams per mole).See the Related Questions for how to convert moles to grams.
How is the number of moles of an element determined froma known mass?
To determine the number of moles of an element from a known mass, you use the element's molar mass (grams per mole). Simply divide the given mass of the element by its molar mass to calculate the number of moles. This relationship is described by the formula: moles = mass (g) / molar mass (g/mol).
How many moles of Pt are in a 455-mg ring of pure platinum?
To find the number of moles of Pt in the ring, you first need to convert the mass of the ring from milligrams to grams (since 1 gram = 1000 milligrams). Then, divide the mass in grams by the molar mass of platinum (approximately 195.08 g/mol) to find the number of moles of Pt in the ring.
How do you get 242lb to milligrams?
To convert pounds to milligrams, you need to know that 1 pound is equal to 453,592 milligrams. Therefore, to convert 242 pounds to milligrams, you would multiply 242 by 453,592 to get 109,740,464 milligrams.
