No problem - first, get the formula for aluminum chromate. The chromate polyatomic ion is CrO4 with a -2 charge. Aluminum has 3 valence electrons, so when it bonds with the chromate poly, the formula must be Al2(CrO4)3. Now, use the Periodic Table to get the molar mass for that formula unit. 2 aluminums, 3 chromiums, and 12 oxygens are 2(27)+3(52)+12(16)=402 grams/mole. You have 3.3 kg, which is 3,300g. Set up a direct proportion: 402g/1mol=3,300g/"x" moles. Solve for "x" to get approx. 8.21 moles of aluminum chromate.
To determine how many moles of aluminum are produced from 33 grams, divide the given mass by the molar mass of aluminum, which is approximately 26.98 g/mol. So, 33 g / 26.98 g/mol ≈ 1.22 moles of aluminum are produced.
The formula of aluminium chloride is AlCl3. The atomic weight of aluminium is 27 and that of chlorine is 35.5. That means 35.5*3 grams of chlorine will combine with 27 grams of aluminium. So 33 grams of chlorine will combine with 8.37 grams of aluminium. The addition of both makes it 41.37 grams. In this reaction, the whole chlorine will be utilized and only part of the aluminium.
each mole contains 6.022*10(raised to the power 23) so three moles of sodium contain 18.066*10(raised to the power 23) mass of one mole of sodium is 11 grams so mass of three moles of sodium is 33 grams
Molarity = moles/litermoles = 9.33 g Na2S x 1 mole/78 g = 0.1196 molesliters = 450 ml x 1L/1000 ml = 0.45 Lmolarity = 0.1196 moles/0.45 L = 0.266 M = 0.27 M (2 sig figs)
There are 33 electrons in an Arsenic atom.
To determine how many moles of aluminum are produced from 33 grams, divide the given mass by the molar mass of aluminum, which is approximately 26.98 g/mol. So, 33 g / 26.98 g/mol ≈ 1.22 moles of aluminum are produced.
how many moles are contained in 4.67 L sample of gas at 33 degrees celcius and 199 kpa
To find the molarity, we first need to convert the mass of water to moles. Since 1 kg of water is approximately 1000 moles, 3 kg of water is 3000 moles. Then, molarity is calculated by dividing the number of moles of solute (NaOH) by the volume of solution in liters. So, the molarity would be 6 moles / 3 L = 2 M.
AlCl3 is soluble in water so to find the solubility of Alcl3 ( not KSp) ,the among of this compound dissolving in definite volume of water should be given.
The number of protons in an atom will always be the same as the atomic number, by which the periodic table is organized. So figuring out how many protons an atom has just becomes an exercise at reading the table. In this case, aluminum has an atomic number of 13. If the particle is specifically an atom, then it will be neutral and the number of electrons will balance the number of protons exactly. The number of neutrons will differ depending on the isotope - atoms of the same element with different numbers of neutrons. Although, almost 100% of aluminum is 27Al with 14 neutrons.
33 feet is 33 feet. If 33 had other units, I feel no pity.
