JordanTo find the mass of 3.60 moles of H2SO4, you first need to calculate the molar mass of H2SO4. The molar mass of H2SO4 is 98.08 g/mol. Multiply the molar mass by the number of moles to get the mass: 3.60 moles * 98.08 g/mol = 353.088 grams. Therefore, the mass of 3.60 moles of H2SO4 is 353.088 grams.

How many hydrogen atoms are in 360 grams of water?
There are 4.8 x 10^24 hydrogen atoms in 360 grams of water. This is calculated by using Avogadro's number to convert the mass of water to moles, and then using the chemical formula of water (H2O) to determine the number of hydrogen atoms present in 1 mole of water.
How many moles of hydrogen form when 4 moles of methane react completely?
The complete combustion of methane proceeds according to the equation: CH4 + 2 O2 = CO2 + 2 H2O. Therefore, each mole of methane produces two moles of water and 4 moles of methane will produce eight moles of water.
What is the Molarity of a solution prepared by diluting 360 ml of 2 M HCl with 120 ml of water?
The moles of HCl in the initial solution is 2 M x 0.36 L = 0.72 moles. When diluted, the total volume becomes 360 ml + 120 ml = 480 ml. Thus, the new molarity is 0.72 moles / 0.48 L = 1.5 M.
What is a harmless substance with a solubility more than 700 grams per liter?
Table salt (sodium chloride) is a harmless substance with a solubility of around 360 grams per liter at room temperature, which can increase at higher temperatures. Sugar (sucrose) is another harmless substance with a solubility of around 2,000 grams per liter at room temperature, making it a good example that fits your criteria.
What is the value of twenty grams of white gold?
The value of white gold depends on its purity (karat) and current market prices. As of 2021, 20 grams of 18K white gold may be worth around $600-$800, while 20 grams of 24K white gold could be worth $900-$1200. It's recommended to check with a jeweler or precious metal dealer for an accurate appraisal.
