The required moles of AgBr precipitate produced by given moles of silver nitrate is 0.0123.

<h3>How do we calculate moles from molarity?</h3>

Molarity of any solution is define as the moles of solute present in per liter of the solution and it will be represented as:
M = n/V

Given that, molarity of AgNO₃ = 0.250M

Volume of AgNO₃ = 49.5mL = 0.0495L

Moles of AgNO₃ = (0.25)(0.0495) = 0.0123mol

Given chemical reaction is:

2AgNO₃(aq) + CaBr(aq) → 2AgBr(s) + Ca(NO₃)₂(aq)

As it is mention that CaBr is present in excess quantity and AgNO₃ is the limiting reagent so the formation of precipitate will depend on the AgNO₃.

From the stoichiometry of the reaction, it is clear that:

2 moles of AgNO₃ = produces 2 moles of AgBr

0.0123 moles of AgNO₃ = produces 2/2×0.0123=0.0123 moles of AgBr

Hence 0.0123 is the required moles of precipitate.

Answer:

2 Answers. The column is filled with the carrier (liquid or gas) before the sample is injected. Thus if there is no interaction between the sample and the column, then the fastest that the sample can get to the detector is the dead time denoted by tM in the diagram.

When an aluminum cube of edge 0.100 m and temperature T0= 5.00°C is submerged in a bucket of water, the level of the water rises
vodka [1.7K]

Answer:

5.52cm³ of water will rise and might spill over the edge

Explanation:

Use the change in volume of a liquid with changing temperature equation which is written as

ΔV = β x V₀ x ΔT, where β is the coefficient of expansion, V₀ is the volume being submerged and ΔT is the difference in temperature

ΔV = (69 x 10⁻⁶) x (0.1 x 0.1 x 0.1) x (85 - 5)

ΔV = 5.52 x 10⁻⁶ m³

ΔV = 5.52cm³
