1. Using the Hoffman apparatus for electrolysis, a chemist decomposes 50.5 g of water into its gaseous elements. How many grams

of oxygen gas should she get (theoretical yield)? 2. Liquid sodium reacts with chlorine gas to produce sodium chloride. You want to produce 453 g of sodium chloride. How many grams of chlorine gas are needed? 3. You eat 160.0 g of glucose (a handful of M&M's). If glucose, C6H12O6, reacts with oxygen gas to produce carbon dioxide and water, how many grams of carbon dioxide will you have to exhale?

Problem page a virus has a mass of ×9.010−12mg and an oil tanker has a mass of ×3.0107kg . use this information to answer the qu
faltersainse [42]
A. The mass of one mole of the virus is calculated by multiplying the mass of a single virus by the Avogadro's number which is equal to 6.022 x 10^23. Performing this operation,

   mass = (9.0 x 10^-12 mg)(6.022 x 10^23) = 5.42 x 10^12 mg

In correct number of significant figures, the answer would only have to be 5.4 x 10^12 mg. 

b. The number of moles of the virus that will have the same mass as the oil tanker is calculated by dividing the mass of the oil tanker by the mass of one mole of the virus. Note that doing division, both would have to have the same units. 

       n = (3.0 x 10^7 kg) / (5.4 x 10^12 mg)(1 g/1000 mg)(1 kg/1000 g)

Simplifying,
               n = 6

In correct number of significant figures, the answer is 6.0.

A compound containing phosphorus and oxygen has a molar mass of 219.9 g/mol and an empirical formula of p2o3. Determine its mole
Softa [21]

Answer:

P₄O₆

Explanation:

The molecular formula is a whole number multiple of the empirical formula. that is, if the mole wt is 219.9 gms/mole and the empirical formula weight is 110 gms/mole*, then the whole number multiple is 219.9/110 = 2 => Molecular formula => (P₂O₄)₂ => P₄O₆.
