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:
baking bread
Explanation:
The presence of yeast makes this catabolic. The yeast is breaking down into smaller units
Data:
solute: ethylene glicol => not ionization
molar mass of ethylene glicol (from internet) = 62.07 g/mol
solute = 400 g
solvent = water = 4.00 kg
m =?
ΔTf = ?
Kf = 1.86 °C/mol
Formulas:
m: number of moles of solute / kg of solvent
ΔTf = Kf*m
number of moles of solute = mass in grams / molar mass
Solution
number of moles of solute = 400 g / 62.07 g/mol = 6.44 moles
m = 6.44 mol / 4 kg = 1.61 m <-------- molality (answer)
ΔTf = 1.86 °C / m * 1.61 m = 2.99 °C <---- lowering if freezing point (answer)
The answer is a bonding agent
