<h2>Question:-</h2>

Density = 11g/cm³, volume = 2cm³. What is the mass ?

<h2>Solution:-</h2>

We know,

${ \boxed{\bf{\rm \red {Mass \: = \: Density \: × \: Volume}}}}$

So, Mass = 11g/cm³ × 2cm³

Mass = 22 g

<h3>The mass is 22 g. [Answer]</h3>

Convert 9.32x 10 23ª atoms of au to moles of au

7nadin3 [17]

Answer:

$\huge\boxed{\sf no.\ of\ moles = 1.55\ moles }$

Explanation:

Given:

Number of atoms = $9.32 \times 10^{23}$ atoms

Avogadro's Number = $6.023 \times 10^{23}$ atom / mol

Required:

Moles = ?

Formula:

$\displaystyle No.\ of\ moles = \frac{no. \ of \ atoms }{avogadro's \ no.}$

Solution:

$\displaystyle no. \ of \ moles = \frac{9.32\times 10^{23}}{6.023 \times 10^{23}}$

no. of moles = 1.55 moles

$\rule[225]{225}{2}$

postnew [5]

Answer:

45.7kj

Explanation:

To calculates the heats of reaction from heats of formation:

∆Hr=£∆Hp -£∆Hr

= £∆Hch3ChOH - £∆HCh2h2+h20

=(-235.1kj)-(+52.47kj/kg + (-241.8kj/kg)

∆H = 45.71kj/kg
