89 grams of Pb(CH3COO)4 is equal to 0,2 moles.
3.99 or 4
The answer is 2,096.10e-4.
40*4=160g
In order to figure this out, you must do dimensional analysis. Here it is: 3.0 moles He x 4.0026 grams/ mole He = 12 grams
The molar mass of nitric acid (HNO3) is 63.01 g/mol. To find the total grams in 4 moles, you would multiply the molar mass by the number of moles: 63.01 g/mol x 4 mol = 252.04 grams. So, there would be 252.04 grams in four moles of nitric acid (HNO3).
I assume by " much " you mean grams tin. Balanced equation first.Sn + 4HCl -> SnCl4 + 2H2Now, find moles HCl by......Molarity = moles of solute/Liters of solution ( 32.0 ml = 0.032 Liters )1.75 M HCl = X moles/0.032 liters= 0.056 moles HCl=============== Now,0.056 moles HCl (1 mole Sn/4 moles HCl)(118.7 grams /1 mole Sn)= 1.7 grams of tin-----------------------
4 gram molecular weights (moles): However many grams four moles* of the solute is. * Hint: four moles of sodium chloride weighs less than four moles of sucrose.
To find the number of moles in 76 grams of fluorine, you first need to determine the molar mass of fluorine, which is approximately 19 grams per mole. Then, you divide the given mass (76 grams) by the molar mass of fluorine to get the number of moles. In this case, 76 grams of fluorine is equal to approximately 4 moles.
Since the molar mass (grams per mole) of H2O is 18.02, the grams of H2O in 4 moles is 72.08g.
To determine the grams of oxygen needed to produce 4.50 moles of NO2, use the coefficients in the balanced equation. In this case, 7 moles of O2 are required to produce 4 moles of NO2. Calculate: (4.50 moles of NO2) * (7 moles of O2 / 4 moles of NO2) = 7.88 moles of O2. Finally, convert moles to grams using the molar mass of O2 (32.00 g/mol): 7.88 moles * 32.00 g/mol = 252.16 grams of O2.
To find the number of moles in 6.071 grams of helium, divide the given mass by the molar mass of helium. The molar mass of helium is approximately 4 grams per mole. Therefore, 6.071 grams / 4 grams/mol ≈ 1.52 moles of helium.
