How many grams of lithium sulfide must be dissolved in 1600 grams of water to make a 2 molal solution?
To make a 2 molal solution, you would need 2 moles of lithium sulfide per 1000g of water. Since you have 1600g of water, you need 2 x (1600 / 1000) = 3.2 moles of lithium sulfide. To find the grams needed, you would multiply the molar mass of lithium sulfide (45.94 + 32.06) by the number of moles needed (3.2) to get 149.12 grams.
A student weighed 0.550 grams of lithium chloride LiCl to use in a reaction How many moles is this?
To find the number of moles in 0.550 grams of LiCl, divide the mass by the molar mass of LiCl, which is approximately 42.4 g/mol. 0.550 g LiCl / 42.4 g/mol LiCl ≈ 0.013 mol LiCl. Therefore, the student has approximately 0.013 moles of LiCl.
How many moles of lithium phosphate are in 51 grams of this substance?
To find the number of moles in 51 grams of lithium phosphate, you first need to determine its molar mass. The molar mass of lithium phosphate (Li3PO4) is 115.79 g/mol. To find the number of moles, divide the given mass by the molar mass: 51 g / 115.79 g/mol ≈ 0.44 moles of lithium phosphate.
How many moles are contained in 444 grams of magnesium chloride?
To find the number of moles in 444 grams of magnesium chloride, you first need to calculate the molar mass of magnesium chloride. The molar mass of MgCl2 is about 95.21 g/mol. Next, calculate the number of moles by dividing the given mass by the molar mass: 444 g / 95.21 g/mol ≈ 4.66 moles of magnesium chloride.
How many moles of water are needed to react with 2.2 moles of Li2O?
The balanced chemical equation for the reaction between water and Li2O is 2 H2O + Li2O -> 2 LiOH. It shows that 2 moles of water react with 1 mole of Li2O. So, 2.2 moles of Li2O would require 4.4 moles of water for complete reaction.
How many grams are in 0.0864 moles of lithium?
To convert moles to grams, you need to know the molar mass of lithium, which is approximately 6.94 g/mol. Multiplying the number of moles (0.0864 mol) by the molar mass (6.94 g/mol) gives you approximately 0.6 grams of lithium.
How many grams are in 3 moles of lithium?
to get the answer just take number of moles you have and multiply it by the molecular mass of the compound which is 22g/mol in lithium oxide's case. 23mol x 22g/mol = 506 g of Li2O
How many moles in 15 grams if lithium?
From the periodic table, lithium has an atomic weight of 6.941. The molar mass of an element is the atomic weight in grams. Therefore, 1 mole Li = 6.941g Li Therefore, moles Li = 15g Li X 1 mole Li/6.941g Li = 2.2 moles Li
How many grams of lithium bromide are present in 25.0 mL of a 0.100 M soution?
To calculate the grams of lithium bromide present in the solution, you would first determine the moles of lithium bromide using the formula: moles = Molarity x Volume (L). Once you have the moles, you can convert it to grams using the molar mass of lithium bromide (86.85 g/mol).
How many grams is contained in 0.27 moles of calcium?
0,27 moles of calcium contain 10,82 g calcium.
How many grams of Li3N can be formed from 1.75 moles of Li?
20,32 g of lithium nitride can be obtained.
How many atoms are in 12.7grams of lithium?
To determine the number of atoms in 12.7 grams of lithium, you need to first calculate the number of moles using the molar mass of lithium (6.94 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert from moles to atoms.
How many grams of lithium sulfide must be dissolved in 1600 grams of water to make a 2 molal solution?
To make a 2 molal solution, you would need 2 moles of lithium sulfide per 1000g of water. Since you have 1600g of water, you need 2 x (1600 / 1000) = 3.2 moles of lithium sulfide.

How many grams does 0.1 moles of lithium weigh?
"The amount of grams in one mole a substance" is themolar mass (the mass of 1 mole) of a substance.The molar mass of Lithium oxide (Li2O) is 29.881 g/molThe molar mass of a compound can be calculated by adding the molar masses of the compound's constituent elements.In this case :molar mass of lithium oxide= 2x(molar mass of lithium)+ (molar mass of oxygen)= 2x(6.941) + 15.999=29.881 g/molNotes:* the molar masses of elements are found in the periodic table. * Notice the subscript "2" in the chemical formula of lithium oxide , Li2O. This subscript indicates that two lithium atoms are involved in each lithium oxide atom.Hence, we multiply the molar mass of of lithium by "2" when calculating lithium oxide's molar mass.
