What is the mass grams of 5.40 moles of lithium?
For an element such as lithium, the technically correct term is "gram atomic mass" instead of "mole", and for lithium, the gram atomic mass is about 6.941. Therefore, the answer to the question is (5.48)(6.941) or 37.5 grams, to the justified number of significant digits.
Molarity of 734 grams of lithium sulfate are dissolved to make 2500ml of solution?
To find the molarity of the solution, first calculate the number of moles of lithium sulfate in 734g. Then, divide the moles by the volume of solution in liters to get the molarity. Remember to convert grams to moles using the molar mass of lithium sulfate (Li2SO4).
How many moles are contained in 25.0 grams of lithium?
15g Li * (1mol Li / 6.941g Li) = 2.16 mol Li
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 mass of 21.5 grams of calcium hydroxide reacts with an excess of phosphoric acid What mass of calcium phosphate could be recovered from solution?
The balanced chemical equation for the reaction between calcium hydroxide and phosphoric acid is: 3Ca(OH)2 + 2H3PO4 -> Ca3(PO4)2 + 6H2O Using the mole ratio from the balanced equation, we find that 1 mole of calcium hydroxide reacts with 2/3 mole of calcium phosphate. First, calculate the number of moles of calcium hydroxide: 21.5g / 74.093g/mol = 0.290 moles Then, use the mole ratio to find the moles of calcium phosphate that can be produced: 0.290 moles * (1 mole Ca3(PO4)2 / 3 moles Ca(OH)2) = 0.097 moles Lastly, convert moles of calcium phosphate to grams: 0.097 moles * 310.176g/mol = 30 grams of calcium phosphate could be recovered.
How many grams are contained in 5.5 moles of aluminum phosphate?
To convert moles to grams, you need to use the molar mass of the substance. The molar mass of aluminum phosphate is 122.94 g/mol. Therefore, for 5.5 moles of aluminum phosphate, you would have 5.5 moles x 122.94 g/mol = 676.17 grams of aluminum phosphate.
318.0 grams of lithium in moles?
To convert grams of lithium to moles, we need to divide the mass of lithium by its molar mass. The molar mass of lithium is approximately 6.94 g/mol. Moles = 318.0 g / 6.94 g/mol = 45.82 moles. Therefore, 318.0 grams of lithium is equivalent to 45.82 moles.
How many moles of lithium are in 20ml of 0.5mM lithium phosphate?
To determine the number of moles of lithium in 20mL of 0.5mM lithium phosphate, first calculate the moles of lithium in 1mL of the solution: 0.5mM = 0.5 mmol/L = 0.5 × 10^-3 mol/L = 5 × 10^-4 mol/L Now, for 20mL: 5 × 10^-4 mol/L × 20 mL = 0.01 moles of lithium
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.
What is the mass in grams of 5.40 moles of lithium?
The molar mass of lithium is approximately 6.94 g/mol. To find the mass of 5.40 moles of lithium, multiply the number of moles by the molar mass: 5.40 moles * 6.94 g/mol = 37.476 g. So, the mass of 5.40 moles of lithium is 37.476 grams.
How many grams in 6.5 moles of aluminum phosphate?
To convert moles to grams, you need to use the molar mass of aluminum phosphate. The molar mass of aluminum phosphate (AlPO4) is 122.98 g/mol. Therefore, 6.5 moles of aluminum phosphate would be 6.5 moles * 122.98 g/mol = 798.37 grams.
How many grams are in 0.658 mole of calcium phosphate?
To find the mass of calcium phosphate (Ca₃(PO₄)₂) in grams for 0.658 moles, first calculate its molar mass. The molar mass of calcium phosphate is approximately 310.18 g/mol. Multiply the number of moles by the molar mass: 0.658 moles × 310.18 g/mol ≈ 204.4 grams. Thus, there are about 204.4 grams of calcium phosphate in 0.658 moles.
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
1 gram equals how many moles?
It depends on what the substance is. For the elements, the number given as the atomic weight for an element on the Periodic Table is also the number of grams/mole. For example, lithium has an atomic weight of 6.941, so one mole of lithium would be 6.941 grams of lithium. In theory you can have a mole of anything -- electrons, ions, shoes, dollar bills, cars, etc...
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 are in 1.25 moles?
To determine the grams in 1.25 moles of a substance, you need to know the molar mass of the substance. By multiplying the number of moles by the molar mass, you can calculate the grams. Without specifying the substance, the answer cannot be determined.
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).
