0.341dm^3 1 mole of any ideal gas occupies a volume of 22.7dm^3 at STP. We will use this fact to work out the volume of oxygen produced. From the equation, we are given the mole ratio …

To find #n# number of atoms in each molecule we use Avogadro's number #6.023xx10^23# We know that #6.023xx10^23# molecules of any substance are equal to its #1# gm mole.

The mass of PbSO₄ is 7.58 g. This is a limiting reactant type of problem. The steps involved are: Write the balanced equation. Identify the limiting reactant. Use conversion factors to convert moles of …

Feb 25, 2018 · Well, it depends on other factors as well... We cannot find the definite volume given your conditions, as the volume also depends on the pressure and the temperature. Given: 0.4 moles of …

May 19, 2017 · Copper has a molar mass of 63.546 g mol−1, which means that 1 mole of copper has a mass of 63.546 g. Now, in order to have 1 mole of copper, you need to have 6.022 ⋅ 1023 atoms of …

#3# moles of ammonium sulfide gives #1# mol of aluminium sulfide Therefore, The number of moles of aluminium sulfide is

See below. We already have a balanced chemical equation, so now the only thing we have to do is the stoichiometry: Step 1: Convert grams of LiOH into moles using its molar mass. "10.0 g LiOH"*((1 mol …

WARNING! Long answer! The molecular formula is "C"_6"H"_5"NO"_2. > I believe the correct vapour density is 61.5. See below. Our first task is to calculate the empirical formula of the compound. The …

See below. First, we need to write the balanced chemical reaction. This will tell us the mole ratio of magnesium metal to hydrogen gas (used in calculation): 3Mg(s) + 2H_3PO_4(aq) -> …

WARNING! Very long answer! Here are my suggestions. > "NaOH": This one is easy. The molar mass of "NaOH" is 40.00 g/mol. Simply transfer 40.00 g of "NaOH" to a 1 L volumetric flask. Add enough …
