Apr 9, 2018 · Now, the molecular weight of "CH"_4 is 16, and that of water is 18. Since the amount of methane combusting is 0.5 moles, we should get a mole of water, i.e. 18 gms of …

Alas, you are wrong. Here are some tips: You got the right number of moles of nitrogen. But for hydrogen you should use a molecular weight of 2 not 6. You do not add up the moles together. …

First, calculate the number of moles. Moles = grams/molecular mass = 180g 180 g mol → grams cancel out = 1 mol There are 12 hydrogen atoms in glucose, and to find the number of atoms …

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 ⋅ …

Use the density to calculate the amount of water. The rest follows from ratios of solute and solvent. Water density is 1.00g/mL at 20'C. So, the total density is the combination of the …

Nov 23, 2015 · Now you multiply this by the molecular mass number to get the weight in milligrams (divide by 1000 to get the grams). Nickel (II)hydroxide may be formed without or …

How do you calculate percent composition of a compound? How can I calculate the percentage by mass of sodium in sodium azide, NaN3 (s); used in automobile air bags? How can percent …

To calculate the molar mass of a compound, multiply the subscript of each element from the formula times the molar mass of the element. The molar mass of an element is its atomic …

The molecular formula is "C"_6"H"_6"O"_2". We first need to determine the empirical formula, which represents the smallest whole number ratio of elements in the compound. We do that by …

Notice the approximation we made earlier this question that the deuteron's weight is twice the weight of neutron the if we want the answer more accurately. Weight of an neutron = …
