What is the molar mass of trinitrotoluene(TNT), C7H5(NO2)3? What is the molar mass of lysozyme? What volume of 0.500 M H2SO4 is needed to react completely with 20.0 mL of 0.458 M LiOH?

The total mass of a pure substance is simply the product of the derived number of moles of the substance and the molar mass. Answer and Explanation: 1 Determine the mass, {eq}\displaystyle m {/eq}, of the given substance by multiplying the number of moles, {eq}\displaystyle n …

Molar mass: The molar mass of compounds helps us to calculate the number of moles of a substance in the given mass of a particular substance, The relation can be expressed as shown below: number of moles, n = {eq}\frac{m}{M} {/eq} where M is the molar mass of the compound and m is the given mass. Answer and Explanation: 1

Jun 6, 2024 · Then, use the molar mass of LiOH (23.95 g/mol for Li, 16.00 g/mol for O, 1.01 g/mol for H) to convert moles to grams. The mass of LiOH required is approximately 21.6 grams. This answer is:

Lithium hydroxide has been used in spaceships to absorb carbon dioxide exhaled by astronauts. Assuming that the product is lithium carbonate, determine what mass of lithium hydroxide is needed to absorb the carbon dioxide from 1.00 L of air containing 30. Lithium hydroxide, LiOH, reacts with carbon dioxide to produce lithium carbonate, Li_{2}CO ...

With this quantity, we can determine the mass of a substance by simply multiplying the number of moles in a sample to its molar mass. Answer and Explanation: 1 For the first problem, we determine the mass of LiOH by multiplying the number of moles, n = 3 mol, to the molar mass, MW = 23.95 g/mol, such that...

Determine the solution volume in mL needed to make a 0.55 M aqueous solution when 10.25 grams of NaOH (molar mass = 39.99 g/mole) is dissolved in water. Determine the solution volume in mL needed to make a 0.55 m aqueous solution when 10.25 grams of NaOH (molar mass = 33.9 g / mole is dissolved in water. Consider a 10 M solution of NaOH.

Jun 16, 2024 · The molar mass of LiOH is 23.95 g/mol for Li, 15.999 g/mol for O, and 1.008 g/mol for H. The molar mass of LiOH is 23.95 + 15.999 + 1.008 = 40.957 g/mol.

Approximately what mass of potassium hydrogen phosphate is needed to react completely with 27.0 mL of 0.09230 M HNO_3 according to the following balanced equation. Round to three significant digits. Use 174.1 g/mol as the molar mass of potassium hydrogen; Sodium phosphate, Na_3PO_4, reacts with HCl to form H_3PO_4 and NaCl.

May 30, 2024 · The molar mass of LiOH is 23.95 g/mol for lithium, 15.999 g/mol for oxygen, and 1.008 g/mol for hydrogen, totaling 41.943 g/mol for LiOH. This means that for every 41.943 grams of LiOH, 44.01 ...
