Molar mass of magnesium is 24gmol-1. mass of 1.5 mg mole 36g.
The mass of 15 moles of tungsten is 2.757,6 g.
The mass of 6.80 moles of magnesium chloride or MgCl2 is 647,435 g.
0.1126g Mg/(24.305g Mg) = 0.004632792 moles Mg You're welcome, noob.
Mass in grams = no of moles x molecular mass. So, mass in grams = 5.2x 56 = 291.2g
To convert grams to moles you need mercury's atomic mass: 200.59 grams/mole. You can then take your measurement and divide it by the atomic mass to get moles.Grams ÷ Atomic mass = Moles50.15 grams ÷ 200.59 grams = 0.2500 moles Hg
6,8 x 95,211 g (molar mass of anhydrous MgCl2)The mass of 6.80 moles of magnesium chloride or MgCl2 is 647,435 g.
The mass of 15 moles of tungsten is 2.757,6 g.
The mass of 6.80 moles of magnesium chloride or MgCl2 is 647,435 g.
0.1126g Mg/(24.305g Mg) = 0.004632792 moles Mg You're welcome, noob.
Mass = Moles x Ar = 12.5 x 24 = 300g
Mass in grams = no of moles x molecular mass. So, mass in grams = 5.2x 56 = 291.2g
the formula is no. moles is mass / molecular mass. As the number of moles is 1, the mass required will be exactly the same as the molecular mass, which is 58.32g
The number of moles present in 165 g of magnesium can be easily found using the molar mass of magnesium.40.3044 g/mol165 g (1 mol/40.3044 g) = 4.09 mol
A sample of 56,4 of magnesium is equal to 2,32 moles.
If you think to the mass of 88,1 moles of magnesium this is 2141,27 g.
The relative molecular mass of magnesium chloride is approximately 60. The molar mass is therefore 60g per mole. Therefore there is 0.42mol of formula units in 2.5 grams.The formula mass of MgCl2 is 24.3 + 2(35.5) = 95.3Amount of MgCl2 = 2.5/95.3 = 0.0262molThere are 0.0262 moles of formula unit in 2.5 grams of magnesium chloride.To get the number (not in moles), multiply the amount in moles by the Avogadro's constant.
To convert grams to moles you need mercury's atomic mass: 200.59 grams/mole. You can then take your measurement and divide it by the atomic mass to get moles.Grams ÷ Atomic mass = Moles50.15 grams ÷ 200.59 grams = 0.2500 moles Hg
