The weight of the 3 lb roast purchased by the housewife is 1,360.78 grams.
<h3>What is weight?</h3>
The weight of an object is the force acting on the object due to gravity.
The weight of an object varies from place to place across the globe due to difference in acceleration due to gravity.
<h3>Weight of the roast in grams</h3>
1 lb ------------> 453.592 grams
3 lb ------------> ?
= (3 x 453.592)
= 1,360.78 grams
Thus, the weight of the 3 lb roast purchased by the housewife is 1,360.78 grams.

Answer:
4.13 moles of Fe will be produced in the reaction
Explanation:
To produce Fe from CO, we need to react Fe₂O₃ and the carbon monoxide.
The reaction is:
Fe₂O₃ + 3CO → 2Fe + 3CO₂
1 mol of iron (III) oxide react to 3 moles of carbon monoxide in order to produce 2 moles of Iron and 3 moles of carbon dioxide.
We assume, the Fe₂O₃ in excess, so we propose this rule of three
3 moles of CO can produce 2 moles of Fe
Therefore 6.20 moles of CO will produce (6.20 . 2)/3 = 4.13 moles of Fe
Answer:
Molecular formulas describe the exact number and type of atoms in a single molecule of a compound. The constituent elements are represented by their chemical symbols, and the number of atoms of each element present in each molecule is shown as a subscript following that element's symbol.
