If lithium carbonate contains 18.8 percent lithium. What mass of lithium is present in a 1.55g of lithium carbonate?
To work out the mass of one element within a compound (ie the mass of Lithium in Lithium Carbonate), first work out the RFM (Relative Formula Mass) of the compound. To do this, look on the periodic table (PT) & add up the RAM (Relative Atomic Mass) of all of the atoms in the compound (the RAM is the larger of the 2 numbers in each box on the PT). So, if the formula for one molecule of Lithium Carbonate is Li2CO3, then the RFM is Li + Li + C + O + O + O = 7 + 7 + 12 + 16 + 16 + 16 = 74 Next work out what percentage of the compound is the element you want to know. So, Lithium accounts for 14 (2 Lithiums = 7 x 2) out of every 74 grams of Lithium Carbonate. As a percentage, this is ( 14 / 74 ) x 100 = 18.9 %. So, 18.9% of 1.55g [ ( 1.55 / 100 ) x 18.9 ] = 0.29g So there is 0.29g of Lithium is 1.55g of Lithium Carbonate.
What is the chemical formula of lithium carbide?
Lithium carbonate or Li2CO3 is a basic (alkaline) salt often used to treat bipolar disorder.
How do you convert 50 g of calcium carbonate into moles?
1. Calculate formula massCalcium carbonate has chemical formula CaCO3.Its formula mass is 40.1 + 12.0 + 3(16.0) = 100.12. Apply formula to calculate number of moles of CaCO3Amount of CaCO3= mass/formula mass= 50/100.1= 0.50mol
How many moles are in 4g of sodium carbonate?
To find the number of moles in 4g of sodium carbonate, first calculate the molar mass of sodium carbonate (Na2CO3), which is 105.99 g/mol. Then, divide the given mass by the molar mass to get the number of moles. Therefore, 4g of sodium carbonate is equivalent to approximately 0.038 moles.
What is the mass percent of nitrogen in ammonium carbonate?
The molecular formula of ammonium carbonate is (NH4)2CO3. The molar mass of nitrogen in ammonium carbonate is 28.02 g/mol. The molar mass of ammonium carbonate is 96.09 g/mol. To calculate the mass percent of nitrogen in ammonium carbonate, you would divide the molar mass of nitrogen by the molar mass of the compound and multiply by 100. This gives a mass percent of nitrogen in ammonium carbonate of around 29.1%.
