Iron has a density of 7.86 g/cm3. Calculate the volume (in dL) of a piece of iron having a mass of 3.11 kg
SpyIntel [72]

Answer:

The volume is 3.96 dL

Explanation:

<u>Step 1: Convert ml to dl</u>

1Liter = 1000ml = 10³ ml

1Liter = 10 dl

⇒ 1 Liter has 1000ml or 10 dl

⇒ The ratio can be written as : 10dl/ 1000ml = 1 dl / 100ml

<u>Step 2: Convert cm³ </u>=

⇒ 1cm³ is equal to 1 ml.

<u>Step 3:  Calculate volume</u>

⇒ We use the formule of density here, which is : Density (p) = mass (g) / volume( cm³)

⇒ 7.86 g/ cm³  = 3110 grams / Volume ( cm³)

⇒Volume = 3110 grams / 7.86g/cm³ = 395.67 cm³

395.67 cm³ = 395.67 ml = 0.39567 L  = 3.96 dL

3.96 dL is reported to three significant digits due to the precision reported for the density.

What mass of ag2co3 could you produce from 12.7 g agno3 assuming that it is the limiting reagent?
zhenek [66]

10.3 g of  Ag_{2} CO_{3} will produce from 12.7 g AgNO_{3}.

In simple terms, a limiting reagent is a reactant that is completely used up in the reaction. 

It is also referred to as a limiting reactant or limiting agent.

Now, according to the question,

Since it is a limiting reagent, it will react fully. 

The mass of AgCO_{3} that will be produced will be:-

Equivalent mole of AgNO_{3} = Equivalent weight of Ag_{2} CO_{3} = 12.7/169.97 = x*2/274x = 10.3 g. 

Hence, 10.3 g of Ag_{2} CO_{3} will be produced.

It is used to restrict the reaction.

It tells you the estimated amount of compound to be used.

It brings quantitative understanding to chemical reactions.
