Identify the metal by comparison to table 2.4 in the textbook
Papessa [141]
Answer is: metal is lead with density of 11,4 g/cm³.
Text that missing: a sample of an unkwown metal has a mass of 35,4 g and a volume of 3,11 cm³.
m(metal) = 35,4 g.
V(metal) = 3,11 cm³.
d(metal) = m(metal) ÷ V(metal)
d(metal) = 35,4÷ g ÷ 3,11 cm³
d(metal) = 11,4 g/cm³.

4.77 l and a mass of 12.88 kg what is the density of the aluminum in grams per cubic centimeter
Montano1993 [528]
V=4,77L=4770mL\\&#10;m=12,88kg=12880g\\\\&#10;d=\frac{m}{V}=\frac{12880g}{4770cm^{3}}\approx2,7\frac{g}{cm^{3}}

You are given 25.00 mL of an acetic acid solution of unknown concentration. You find it requires 35.75 mL of a 0.2750 M NaOH sol
oksano4ka [1.4K]

Answer:

a. 0.393M CH₃COOH.

b. 2.360% of acetic acid in the solution

Explanation:

The reaction of acetic acid (CH₃COOH) with NaOH is:

CH₃COOH + NaOH → CH₃COO⁻ + H₂O + Na⁺

<em>That means 1 mole of acid reacts per mole of NaOH.</em>

Moles of NaOH to reach the equivalence point are:

35.75mL = 0.03575L × (0.2750mol / L) = <em>9.831x10⁻³ moles of NaOH</em>

As 1 mole of acid reacts per mole of NaOH, moles of CH₃COOH in the acid solution are 9.831x10⁻³ moles.

a. As the volume of the acetic acid solution is 25.00mL = 0.02500L, the molarity of the solution is:

9.831x10⁻³ moles / 0.02500L =

<h3>0.393M CH₃COOH</h3>

b. Molar mass of acetic acid is 60g/mol. The mass of 9.831x10⁻³ moles is:

9.831x10⁻³ moles ₓ (60g / mol) = <em>0.590g of CH₃COOH</em>.

As volume of the solution is 25.00mL, the percentage of acetic acid is:

(0.590g CH₃COOH / 25.00mL) ₓ 100 =

<h3>2.360% of acetic acid in the solution</h3>

you and your friends are at the park on a sunny day, and you are playing on the slide. As you sold down, the hot slide burns you
zzz [600]
Metal is a great conductor of heat while rope does not collect heat from the radiation from the sun as much or contain it while if metal is out in the sun all day it just keeps getting hotter and hotter and when you touch the rope it does not have much heat to transfer but the metal slide is hot enough to irritate your skin

It is composed of an alloy that is 90% Platinum and 10% Iridium; having a density of 21.186 g/cm3. What is the volume of the Sta
oksian1 [2.3K]
The alloy has a density of 21.186g/cc. So for a kilogram or 1000 grams/21.186 g/cc= 45.7 cc. So the answer is 45.7 cc of the allow to make up a kilogram which shows that the density of the allow can be used to calculate the volume of a larger mass ie the kilogram.
